This volume of Studies in Mycology is dedicated to Amy Y. Rossman, who published fundamental papers revising numerous genera and species in the Hypocreales. This issue contains five contributions treating fungi in the families Hypocreaceae and Nectriaceae in the order Hypocreales.  The plant pathogenic genus Calonectria represents a serious threat to the growth and sustainability of plantation forestry of Eucalyptus in both Brazil and Southeastern China. Both contributions treating Calonectria in this issue highlight the high species diversity in relatively small areas surveyed. A total of 38 novel Calonectria spp. (20 from Brazil and 18 from China) are introduced associated with a single genus, which in itself is very surprising. In Colombia, isolations from various Pinus species in plantations and nurseries displaying pitch canker disease symptoms resulted in the identification of more than 10 novel Fusarium species, five of which were provided with names.  Pathogenicity results showed that two of the novel Fusarium taxa described, displayed levels of pathogenicity comparable to F. circinatum, therefore posing a new risk to commercial Pinus forestry in Colombia and other parts of the world. The genus Trichoderma is treated based on a large-scale survey of plant and fungal material conducted in Southern Europe and Macaronesia. A morphological and phylogenetic study allowed for the recognition of more than 90 species, of which 17 are newly described. Furthermore, Aphysiostroma stercorarium is combined in Trichoderma and a genus-wide phylogeny based on fragments of the RNA polymerase II subunit B and larger subunit of ATP citrate lyase gene regions are presented. The ascomycete family Nectriaceae includes numerous important plant and human pathogens, as well as several species used extensively in industrial and commercial applications. To address the poorly defined generic and species concepts in this family, a robust phylogenetic study using 10 loci was conducted for available type and authentic strains of genera known in Nectriaceae. For several of these genera, no sequence data were previously available, and therefore this contribution represents the largest sampling of nectriaceous fungi subjected to multi-locus sequence analyses to date. Forty-seven genera, of which six are new, and one new family, Tilachlidiaceae, were resolved. Additionally, several genera were proposed for synonymy based on the abolishment of dual nomenclature. This contribution provides a broad phylogenetic backbone and framework for future studies of the Nectriaceae.

This volume of Studies in Mycology focuses on emerging and established fungal diseases that pose a serious threat to global food and fibre supply. The issue contains six contributions, including a revision of the genus Bipolaris, which has species that are commonly associated with leaf spots, leaf blights, root and foot rots of field crops in the Poaceae, including rice, maize, wheat and sorghum. In total 47 species are accepted, and a taxonomic key provided for their morphological identification. Species of Colletotrichum in the C. destructivum species complex associated with anthracnose diseases of important crops such as clover, alfalfa, cowpea and lentil are also treated, and eight new species are introduced. The genus Pestalotiopsis encompasses fungi that are commonly isolated as endophytes, but also include a number of phytopathogens that cause a variety of post-harvest diseases, fruit rots and leaf spots, as well as other emerging diseases. Pestalotiopsis is delineated from two novel genera, namely Neopestalotiopsis and Pseudopestalotiopsis, and 35 novel species are introduced, along with several new combinations to emend monophyly of these genera. The genus Alternaria is also omnipresent, causing disease on a range of agriculturally important crops. Alternaria section Porri is the largest section in the genus, containing almost all Alternaria species with medium to large conidia and long beaks, some of which are important plant pathogens (e.g. Alternaria porri, A. solani and A. tomatophila). Based on a multi-gene phylogenetic study, 63 species are delineated, of which 10 are newly described, and 27 species names are synonymised. Species of Pyricularia are responsible for major diseases on Poaceae, including rice, wheat and millet. To clarify the taxonomic relationships among species that are magnaporthe- orpyricularia-like in morphology, the phylogenetic relationships among isolates representing a wide range of host plants are analysed. Species of Pyricularia s. str. are shown to belong to a monophyletic cladedefining the Pyriculariaceae, which is sister to the Ophioceraceae,representing two novel families distinct from the Magnaporthaceae. Furthermore, 10 novel genera, and seven novel species are also introduced, along with a re-evaluation of generic and species concepts within the Pyriculariaceae. The genus Ceratocystis s. l. (Ceratocystidaceae) includes serious plant pathogens, significant insect symbionts and agents of timber degradation that result in substantial economic losses. Based on a multi-gene phylogeny of 79 species residing in Ceratocystis s. l.,seven genera could be distinguished, including two novel genera, Davidsoniella and Huntiella. In total, 30 new combinations are introduced, providing a stable platform for the Ceratocystidaceae.

Abstract

This issue contains six articles describing the ecology, diversity, nomenclature and new taxonomic concepts of Aspergillus, Penicillium and Talaromyces.

Aspergillus section Circumdati or the Aspergillus ochraceus group, includes species with rough walled stipes, biseriate conidial heads, yellow to ochre conidia and sclerotia that do not turn black. A polyphasic approach was applied using morphological characters, extrolite data and partial calmodulin, β-tubulin and ITS sequences to examine the evolutionary relationships within this section. Based on this approach the section Circumdati is revised and 27 species are accepted, introducing seven new species. 13 species of section Circumdati produce large amounts of ochratoxin A while seven additional species produce ochratoxin A inconsistently and/or in trace amounts: The most important species regarding potential ochratoxin A contamination in agricultural products are A. ochraceus, A. steynii and A. westerdijkiae.

In the second article, analyses of dust samples collected from nine countries were made using the culture-dependent dilution-to-extinction method. Of the 7904 isolates obtained, 2717 isolates were identified as belonging to Aspergillus, Penicillium and Talaromyces. Isolates represented 59 Aspergillus species, including eight undescribed species, 49 Penicillium species with seven undescribed species and 18 Talaromyces species with three new taxa.

In the next two articles the phylogeny and new single nomenclature of Aspergillus and Penicillium are discussed. Aspergillus was traditionally associated with nine teleomorph genera, but phylogenetic data suggest that together with genera such as Polypaecilum, Phialosimplex, Dichotomomyces and Cristaspora, Aspergillus forms a monophyletic clade closely related to Penicillium. Changes in the International Code of Nomenclature for algae, fungi and plants resulted in the move to one name per species, meaning that a decision had to be made whether to keep Aspergillus as one big genus or to split it into several smaller genera. In a vote, the International Commisions of Penicillium and Aspergillus chose to keep Aspergillus. The aim of this paper was to introduce new combinations for accepted species presently lacking an Aspergillus name and provide an updated accepted species list for the genus, now containing 339 species. In addition, a standard working technique for the identification of Aspergillus and Penicillium is recommended. For Aspergillus calmodulin is proposed as a secondary identification marker, while for Penicillium β-tubulin is proposed. Penicillium currently contains 354 accepted species, including new combinations for Aspergillus crystallinus, A. malodoratus and A. paradoxus, which belong to Penicillium section Paradoxa. Both papers contain a detailed list of the accepted species together with corresponding MycoBank number, living ex-type strains and provide GenBank accession numbers to ITS, β-tubulin, calmodulin and RPB2 sequences.

In the fifth paper, a new monograph on Talaromyces applying a polyphasic species concept, including morphological, molecular and physiological characters is presented. Based on an ITS, β-tubulin and RPB2 multigene phylogeny, a new sectional classification for the genus is proposed, placing the 88 accepted species into seven sections, named sections Bacillispori, Helici, Islandici, Purpurei, Subinflati, Talaromyces and Trachyspermi. All accepted species are illustrated and described in detail, as well as notes provided on their identification using morphology and DNA sequences. For molecular identification, β-tubulin is proposed as a secondary molecular marker.

Species belonging to Penicillium section Aspergilloides have a world-wide distribution with P. glabrum, P. spinulosum and P. thomii being the most well-known species of this section. In the present study, 349 strains belonging to section Aspergilloides were subjected to multilocus molecular phylogenetic analyses using partial β-tubulin, calmodulin and RNA polymerase II second largest subunit (RPB2) sequences. Section Aspergilloides is subdivided into 12 clades and 51 species. Twenty-five species are described here as new. The most important characters to distinguish these species were colony sizes on agar media, growth on CYA at 30 °C, ornamentation and shape of conidia, sclerotium production and stipe roughness.

The present study presents a monograph of Daldinia, employing a polyphasic approach. Several thousand herbarium specimens, and several hundreds of freshly collected and cultured specimens of Daldinia and allied Xylariaceae, originating from around the world, were studied for morphological traits, including by SEM, and chemically by HPLC profiles using UV visible and mass spectrometric detection.

Six new species of Daldinia from the tropics and the Southern Hemisphere are described. Daldinia asphalatum is resurrected, and D. cudonia is regarded as its synonym. In addition, the following binomials are typified: Daldinia asphalatum, D. caldariorum, D. clavata, D. cuprea, D. durissima, D. eschscholtzii, D. grandis, D. loculata, and D. vernicosa. Annellosporium and Versiomyces are regarded as synonyms of Daldinia. Many new synonymies in Daldinia are proposed, and some previously published names are rejected. In total, 47 taxa in Daldinia are recognised and a key is provided. Their biogeography, chorology, and ecology, as well as the importance of their secondary metabolites, are also discussed.

Daldinia is segregated into five major groups based on phenotypic characteristics. A preliminary molecular phylogeny based on 5.8S/ITS nrDNA was found to be in agreement with the above-mentioned segregation of the genus, based on morphological and chemotaxonomic evidence.

Interestingly, these phylogenetic findings correlate with chemotaxonomic characters to a great extent, especially regarding the distribution of marker metabolites in their mycelial cultures. Hence, the current study revealed that fungal secondary metabolite profiles can have taxonomic value beyond the species rank and even coincide with phylogenetic data.

This volume of Studies in Mycology is dedicated to Robert (Bob) A. Shoemaker, who monographed several important genera of Dothideomycetes, and also published fundamental papers revising species and genera in the Botryosphaeria complex. The issue contains three contributions dealing with a revision of the Botryosphaeriales, an order containing plant pathogenic fungi of quarantine and economic importance. In the first paper the Phyllostictaceae is resurrected for Phyllosticta, the generic name chosen over Guignardia for this genus of fungi. By employing a multi-gene phylogenetic analysis on 129 isolates, 12 new species are introduced, while epitype and neotype specimens are designated for a further seven species. One species of interest is P. citrimaxima associated with tan spot of Citrus maxima fruit in Thailand, which adds a fifth species to the citrus black spot complex. Other than the Phyllostictaceae, a further five families are recognised in the second paper, including the newly introduced Aplosporellaceae (Aplosporella and Bagnisiella), Melanopsaceae (Melanops), and Saccharataceae (Saccharata). Furthermore, molecular clock dating on radiations within the Botryosphaeriales, based on estimated mutation rates of the rDNA SSU locus, suggests that the order originated in the Cretaceous period around 103 (45–188) mya, with most of the diversification in the Tertiary period. In the third paper an account is given of all genera and species in the Botryosphaeriaceae known from culture. Included is a historical overview of the family, the morphological features that define the genera and species and detailed descriptions of the 17 genera and 110 species. Keys to the genera and species are also provided, along with definitive DNA barcodes for the species in each genus.

This volume of Studies in Mycology is dedicated to the plant health officers of the world, who are constantly confronted by a range of plant pathogenic fungi that cause devastating diseases of agricultural and forestry crops. Five main groups of fungi are dealt with, namely Alternaria, Cercospora, Phoma, Pseudocercospora and Septoria. In the first paper Phoma sections Plenodomus, Heterospora and Pilosa were reinvestigated, resulting in the introduction of several novel genera and species. The second paper deals with the paraphyletic genus Pseudocercospora; host specificity was considered for 146 species of Pseudocercospora occurring on 115 host genera from 33 countries. From these results we concluded that the application of European and American names to Asian taxa, and vice versa, was often not warranted. The third paper deals with the genus Cercospora, which contains more than 5 000 different species. Isolates used in the molecular phylogeny were obtained from 161 host species, 49 host families and 39 countries. Although some species were found to host-specific, others were isolated from a wide host range. The fourth paper deals with phylogenetic lineages within the genus Alternaria, which was revealed to represent a well-supported node containing 24 internal clades and six monotypic lineages. Several genera were placed in synonymy with Alternaria, for which 16 new sections were proposed. Two papers deal with the genus Septoria, which was shown to be poly- and paraphyletic, leading to the introduction of 15 new genera, and more than 40 new species. Although some species were shown to be highly specific, other taxa were revealed to occur on hosts in more than six different plant families. For all taxa investigated multi-gene DNA data were deposited in GenBank and other databases to expedite future identification of these plant pathogenic fungi. No single locus was found to be the ideal DNA barcode gene for these taxa, and species identification will have to be based on a combination of gene loci and morphological characters.

This Issue of Studies in Mycology deals with vegetative growth and development of Aspergillus in general and A. niger in particular. Aspergillus niger is a member of the Aspergillus section Nigri, a group of 26 species that are dubbed “the black Aspergilli”. Aspergillus niger is a cosmopolitan fungus. It can be isolated from all continents and is not very selective with respect to environmental conditions. Aspergillus niger is used as a cell factory for the production of enzymes and metabolites such as organic acids.

This Issue starts with a review on molecular mechanisms underlying differentiation processes in the vegetative mycelium and during asexual and sexual development of aspergilli.

The articles of van Leeuwen et al. show that the RNA composition of dormant conidia is highly different from that of germinating conidia (i.e. of conidia during isotropic and polarized growth). The transcriptome of conidia changes most dramatically during the first two hours of germination enabling initiation of protein synthesis and respiration. The antifungal natamycin does neither affect differential expression of genes nor germination of A. niger conidia during the first 2 h of the process. Notably, subsequent stages of germination were effectively blocked by the anti-fungal and the transcriptome inside the cells had changed thoroughly. The article of van Veluw et al. focusses on stages following germination namely the formation of micro-colonies. It is shown that micro-colonies of a control strain are smaller and more heterogeneous in size when compared to strains in which pigmentation genes are inactivated. These results are of interest from a biotechnological point of view since productivity is related to the morphology of micro-colonies. The results of Van Veluw et al. also indicate the existence of transcriptionally and translationally highly active and lowly active hyphae in 1 mm wide micro-colonies of A. niger as was previously shown in macro-colonies with a diameter of about 5-7 cm. However, the existence of distinct populations of hyphae with high and low transcriptional and translational activity seems to be less robust when compared to macro-colonies. Why colonies have hyphae with different transcriptional and translational activity is still not clear but it may have a role in survival in an environment where conditions are dynamic. The article of Bleichrodt et al. focusses on sporulating colonies. Evidence is presented that GFP but not mRNA streams from the vegetative mycelium to conidiophores. Apparently, flow of molecules to the reproductive structure is selective. Absence of RNA streaming would explain why distinct RNA profiles were found in the aerial mycelium when compared to the vegetative mycelium. Future studies should reveal why GFP flows but mRNA does not.

This volume of Studies in Mycology is dedicated to Brian C. Sutton, in honour of his scientific contributions to our present understanding of the genus Colletotrichum, and for providing a framework for morphology-based identification of taxa in the genus. The volume consists of contributions that revise three of the major Colletotrichum species complexes, and a concluding paper that summarises the present situation. It provides an online identification tool to all presently recognised species, and also gives insight into future research directions. The research papers continue the trend of applying multi-locus phylogenetics to elucidate cryptic species complexes, and in the process designates numerous epitype specimens to fix the genetic application of names. Furthermore, numerous novel taxa are introduced in the C. acutatum (treating 31 taxa, and introducing 21 novel species), C. boninense (treating 17 taxa, and introducing 12 novel species), and C. gloeosporioides (treating numerous taxa of which 22 are accepted, and introducing 9 novel taxa, as well as one novel subspecies) species complexes. Although some species appear to have preferences to specific hosts or geographical regions, others are plurivorous and are present in multiple regions. The future for Colletotrichum biology will thus have to rely on consensus classification and robust online identification tools. In support of these goals, a Subcommission on Colletotrichum has been formed under the auspices of the International Commission on Taxonomy of Fungi, which will administer a carefully curated barcode database for sequence-based identification of species within the BioloMICS web environment.

A monographic revision of the hyphomycete genus Cladosporium s. lat. (Cladosporiaceae, Capnodiales) is presented. It includes a detailed historic overview of Cladosporium and allied genera, with notes on their phylogeny, systematics and ecology. True species of Cladosporium s. str. (anamorphs of Davidiella), are characterised by having coronate conidiogenous loci and conidial hila, i.e., with a convex central dome surrounded by a raised periclinal rim. Recognised species are treated and illustrated with line drawings and photomicrographs (light as well as scanning electron microscopy). Species known from culture are described in vivo as well as in vitro on standardised media and under controlled conditions. Details on host range/substrates and the geographic distribution are given based on published accounts, and a re-examination of numerous herbarium specimens. Various keys are provided to support the identification of Cladosporium species in vivo and in vitro. Morphological datasets are supplemented by DNA barcodes (nuclear ribosomal RNA gene operon, including the internal transcribed spacer regions ITS1 and ITS2, the 5.8S nrDNA, as well as partial actin and translation elongation factor 1-α gene sequences) diagnostic for individual species. In total 993 names assigned to Cladosporium s. lat., including Heterosporium (854 in Cladosporium and 139 in Heterosporium), are treated, of which 169 are recognized in Cladosporium s. str. The other taxa are doubtful, insufficiently known or have been excluded from Cladosporium in its current circumscription and re-allocated to other genera by the authors of this monograph or previous authors.

Although Nectria is the type genus of Nectriaceae (Hypocreales, Sordariomycetes, Pezizomycotina, Ascomycota), the systematics of the teleomorphic and anamorphic state of Nectria sensu Rossman has not been studied in detail. The objectives of this study are to 1) provide a phylogenetic overview to determine if species of Nectria with Gyrostroma, Tubercularia, and Zythiostroma anamorphs form a monophyletic group; 2) define Nectria, segregate genera, and their species using morphologically informative characters of teleomorphic and anamorphic states; and 3) provide descriptions and illustrations of these genera and species. To accomplish these objectives, results of phylogenetic analyses of DNA sequence data from six loci (act, ITS, LSU, rpb1, tef1 and tub), were integrated with morphological characterisations of anamorphs and teleomorphs. Results from the phylogenetic analyses demonstrate that species previously regarded as the genus Nectria having Gyrostroma, Tubercularia, and Zythiostroma anamorphs belong in two major paraphyletic clades. The first major clade regarded as the genus Pleonectria contains 26 species with ascoconidia produced by ascospores in asci, perithecial walls having bright yellow scurf, and immersed or superficial pycnidial anamorphs (Zythiostroma = Gyrostroma). A lineage basal to the Pleonectria clade includes Nectria miltina having very small, aseptate ascospores, and trichoderma-like conidiophores and occurring on monocotyledonous plants. These characteristics are unusual in Pleonectria, thus we recognise the monotypic genus Allantonectria with Allantonectria miltina. The second major clade comprises the genus Nectria sensu stricto including the type species, N. cinnabarina, and 28 additional species. Within the genus Nectria, four subclades exist. One subclade includes species with sporodochial anamorphs and another with synnematous anamorphs. The other two paraphyletic subclades include species that produce abundant stromata in which the large perithecia are immersed, large ascospores, and peculiar anamorphs that form pycnidia or sporodochia either on their natural substrate or in culture. In this study the evolution of species, morphology, and ecology of the three genera, Allantonectria, Nectria, and Pleonectria, are discussed based on the phylogenetic analyses. In addition, descriptions, illustrations, and keys for identification are presented for the 56 species in Allantonectria, Nectria, and Pleonectria.

Species of the Trichocomaceae occur commonly and are important to both industry and medicine. They are associated with food spoilage and mycotoxin production and can occur in the indoor environment, causing health hazards. Some species are opportunistic pathogens, while others are exploited in biotechnology for the production of enzymes, antibiotics and other products. In this study, the relationship of Penicillium to other genera of the Trichocomaceae was investigated and studied in detail the phylogeny of the genus itself. In order to study these relationships, partial RPB1, RPB2, Tsr1 and Cct8 gene sequences were obtained. Phylogenetic analysis shows that Penicillium is polyphyletic. The genus is re-defined and a monophyletic genus for both anamorphs and teleomorphs is created (Penicillium sensu stricto). The genera Thysanophora, Eupenicillium, Chromocleista, Hemicarpenteles and Torulomyces are accommodated in Penicillium s. str. and new combinations for the species belonging to these genera are proposed. Analysis of Penicillium below genus rank revealed the presence of 25 clades. A new classification system including both anamorph and teleomorph species is proposed and these 25 clades

Species of Penicillium section Citrina have a worldwide distribution and occur commonly in soils. In the present study, more than 250 isolates presumably belonging to section Citrina were examined using a combined analysis of phenotypic and physiological characters, extrolite profiles and ITS, β-tubulin and/or calmodulin sequences. Section Citrina includes 39 species, and 17 of those are described as new.

Multigene phylogenetic analyses with the ITS region, cox1, β-tubulin, elongation factor 1-α, and calmodulin, reveal that the P. sclerotiorum morphospecies is a complex of seven phylogenetically distinct species, three of which were recently described, namely P. guanacastense, P. mallochii, and P. viticola. Three previously unidentified species are described here as P. cainii, P. jacksonii, and P. johnkrugii.

The taxonomic history of anamorphic species attributed to Penicillium subgenus Biverticillium is reviewed, along with evidence supporting their relationship with teleomorphic species classified in Talaromyces. Following the concepts of nomenclatural priority and single name nomenclature, all accepted species of Penicillium subgenus Biverticillium were transfer to Talaromyces. A list of accepted Talaromyces names and newly combined Penicillium names is given. Species of biotechnological and medical importance, such as P. funiculosum and P. marneffei, are now combined in Talaromyces. Excluded species and taxa that need further taxonomic study are discussed.

Four new species, Aspergillus eucalypticola, A. neoniger, A. fijiensis and A. indologenus are described and illustrated. Two other species, A. violaceofuscus and A. acidus, are revalidated based on molecular and extrolite data. Two other species described previously, A. coreanus and  A. lacticoffeatus, were found to be colour mutants of A. acidus and A. niger, respectively. Methods which could be used to distinguish the two closely related and economically  important species A. niger and A. awamori are also detailed.

Wild type Aspergillus niger isolates from different biotopes from all over the world were compared to each other and to the type strains of other black Aspergillus species with respect to growth and extracellular enzyme profiles. The origin of the A. niger isolate did not result in differences in growth profile with respect to monomeric or  polymeric carbon sources. Differences were observed in the growth rate of the A. niger isolates, but these were observed on all carbon sources and not specific for a particular  carbon source. In contrast, carbon source specific differences were observed between the different species. The data indicate that the local environment does not result in stable adaptations of A. niger with respect to growth profile or enzyme production, but that the potential is  maintained irrespective of the environmental.

D-xylose and L-arabinose are highly abundant components of plant biomass. In this study, the L-arabinose responsive transcriptional activator (AraR) is identified in Aspergillus niger and was shown to control the L-arabinose catabolic pathway as  well as expression of genes encoding extracellular L-arabinose releasing enzymes.  AraR was only identified in the Eurotiales, more specifically in the family Trichocomaceae and appears to have originated from a gene duplication event (from XlnR) after  this order or family split from the other filamentous ascomycetes. XlnR is present in all filamentous ascomycetes with the exception of members of the Onygenales. Since  the Onygenales and Eurotiales are both part of the subclass Eurotiomycetidae, this indicates that strong adaptation of the regulation of pentose utilisation has occurred at  this evolutionary node.

Section Terrei of Aspergillus was studied and based on phylogenetic analysis of calmodulin and  β-tubulin sequences seven lineages were observed among isolates that have previously been treated as A. terreus and its subspecies. Aspergillus alabamensis, A. terreus var. floccosus, A. terreus var. africanus, A. terreus var. aureus, A. hortai and A. pseudoterreus all represent distinct lineages from the  A. terreus clade. New names are proposed for A. terreus var. floccosus, A. terreus var. africanus, A. terreus var. aureus, while Aspergillus hortai is recognised at species level.

A polyphasic approach was applied using morphological characters, extrolite data and partial  calmodulin, β-tubulin and ITS sequences to examine the evolutionary relationships Aspergillus subgenus Circumdati section Flavi. The data indicate that Aspergillus section Flavi involves 22 species,  which can be grouped into seven clades. Two new species, A. pseudocaelatus sp. nov. and A. pseudonomius sp. nov. have been discovered, and can be distinguished from  other species in this section based on sequence data and extrolite profiles.
Based on phylogenetic analysis of sequence data, Aspergillus section Usti includes 21 species, including two teleomorphic species Aspergillus heterothallicus (= Emericella heterothallica) and Fennellia monodii. Aspergillus germanicus Aspergillus carlsbadensis, Aspergillus californicus, A. pseudoustus and A. turkensis are described a new taxa.

This volume of Studies in Mycology is a successor to a previous issue “Molecules, Morphology and Classification: Towards Monophyletic Genera in the Ascomycetes” (vol. 45, edited by Seifert, Gams, Crous & Samuels 2000). In this volume authors integrated new DNA phylogenetic information into an existing classification system, complicated by the need to accommodate fungal pleomorphy. The present volume continues the trend of applying multigene phylogenetics to generic and species concepts, extending the higher taxonomic level studies of the Assembling the Fungal Tree of Life project into a more finely resolved realm. Another controversy of contemporary ascomycete taxonomists, namely the issue of dual nomenclature, is also addressed in this issue, with authors of papers adopting five different interpretations of One Fungus: One Name. Option 1 – Strict priority. Strict application of priority of both generic names and species epithets, irrespective of whether these names were originally typified by anamorphic or teleomorphic elements. Following the lead primarily initiated by Lombard et al. (Stud. Mycol. 66, 2010), this approach was followed here by Gräfenhan et al. and Schroers et al. in their revisions of parts of Fusarium sensu Wollenweber and Acremonium by Summerbell et al. Option 2 – Teleomorph priority with anamorphic species epithets. This option maintains the primacy of teleomorph names at both the genus and species rank. It was exercised in part by Chaverri et al. in their revision of Neonectria sensu lato, and the associated anamorph genera Cylindrocarpon and Campylocarpon. Option 3 – Teleomorph priority with earlier anamorph species epithets not considered. This practice was followed by Hirooka et al. in their revision of Nectria cinnabarina, in parts of the revision of Neonectria by Chaverri et al., the revision of Plagiostoma by Meija et al., and the description of the new species Guignardia korthalsellae by Sultan et al. Option 4 – Teleotypification. In this issue, this approach was followed by Réblová & Seifert, who changed the originally hyphomycetous status of Sterigmatobotrys to holomorphic status by epitypification. Option 5 – Single species names but allowing two genera per clade. This option is completely consistent with the requirements of the present Code. In this issue, Põldmaa followed this practice in her revision of tropical species of Hypocrea and related Cladobotryum anamorphs. All papers focus on Ascomycete systematics, and pay homage to the craft of the honoree, Gary Samuels, i.e. an attention to quality illustrations, complete descriptions, anamorph-teleomorph connections, and species-level molecular phylogenetics.

The genus Cladosporium is one of the largest genera of dematiaceous hyphomycetes, and is characterised by a coronate scar structure, conidia in acropetal chains and Davidiella teleomorphs. Based on morphology and DNA phylogeny, the species complexes of C. herbarum and C. sphaerospermum have been resolved, resulting in the elucidation of numerous new taxa. In the present study, more than 200 isolates belonging to the C. cladosporioides complex were examined and phylogenetically analysed on the basis of DNA sequences of the nuclear ribosomal RNA gene operon, including the internal transcribed spacer regions ITS1 and ITS2, the 5.8S nrDNA, as well as partial actin and translation elongation factor 1-α gene sequences. For the saprobic, widely distributed species Cladosporium cladosporioides, both a neotype and epitype are designated in order to specify a well established circumscription and concept of this species. Cladosporium tenuissimum and C. oxysporum, two saprobes abundant in the tropics, are epitypified and shown to be allied to, but distinct from C. cladosporioides. Twenty-two species are newly described on the basis of phylogenetic characters and cryptic morphological differences. The most important phenotypic characters for distinguishing species within the C. cladosporioides complex, which represents a monophyletic subclade within the genus, are shape, width, length, septation and surface ornamentation of conidia and conidiophores; length and branching patterns of conidial chains and hyphal shape, width and arrangement. Many of the treated species, e.g., C. acalyphae, C. angustisporum, C. australiense, C. basiinflatum, C. chalastosporoides, C. colocasiae, C. cucumerinum, C. exasperatum, C. exile, C. flabelliforme, C. gamsianum, and C. globisporum are currently known only from specific hosts, or have a restricted geographical distribution. A key to all species recognised within the C. cladosporioides complex is provided.

OrderSystematics of Calonectria: a genus of root, shoot and foliar pathogens

Species of the genus Calonectria (Hypocreales) are important plant pathogens, several of which have a worldwide distribution. Taxonomic studies on these fungi have chiefly relied on DNA sequence comparisons of the β-tubulin (BT) gene region, because the ITS gene has proven inordinately conserved to facilitate species discrimination. There are about 68 species of Calonectria associated with root, stem and leaf diseases of numerous plant hosts. Attempts to resolve species boundaries have resulted in a multigene database employing seven gene regions including actin (ACT), BT, calmodulin (CAL), histone H3 (HIS3), ITS, translation elongation 1-alpha (TEF-1α) and the 28S large subunit RNA gene, for all species. Although the BT gene region provided valuable insights into relationships among species of Calonectria, analyses of individual coding gene regions and single nucleotide polymorphisms showed that CAL sequence data provided the best resolution in distinguishing between them. Sequence data for the TEF-1α, HIS3, BT and ACT gene regions were less useful. This issue contains three papers, and describes 10 novel species. All names formerly accommodated in the genus Cylindrocladium are combined into the older generic name, Calonectria, representing a single name for this monophyletic genus. Dichotomous and synoptic keys to all Calonectria spp. currently recognised are also provided.
