Order (1). On certain species of Mucor with a key to all accepted species. (2). On the genera Rhizomucor and Parasitella.
Author:M. A. A. SCHIPPER:
Details: 70pp., paperback, 1978
Price: € 15,-

Treated are all species of Mucor known in culture and not discussed in three earlier papers (Schipper, 1973, 1975, 1976). Described are 21 species and varieties, four of which are new taxa (Mucor amphibiorum, M. tuberculisporus, M. variosporus, M. zychae var. linnemanniae) and one is validated (M. prayagensis). The rather unusual results of interspecific contrasts in the described taxa are discussed in connection with literature data. A key is given to all accepted Mucor species, varieties and formae; 49 taxa are considered. The genus Rhizomucor is reintroduced for the 3 thermophilic species, Rhizomucor pusillus, Rh. miehei and Rh. tauricus. The genus is distinct from Mucor by the formation of stolons and rhizoids and by its temperature requirements. The genus Parasitella is accepted for the single species, Parasitella parasitica.

Identification of wood-inhabiting Aphyllophorales in pure culture
Author: J.A. Stalpers
Details: 248pp., paperback, 1978

A descriptive analytical key is given of about 550 species of wood-inhabiting Aphyllophorales classified in the families Auriscalpiaceae, Bondarzewiaceae, Coniophoraceae, Corticiaceae, Echinodontiaceae, Fistulinaceae, Ganodermataceae, Hericiaceae, Hymenochaetaceae, Lachnocladiaceae, Polyporaceae, Punctulariaceae, Schizophyllaceae, Sparassidaceae and Stereaceae. Each species is characterized by a numerical code referring to 96 characters or circumscribed parts of characters. The species codes can be transferred to punch cards and thus the system can be easily used as a synoptic key. As main differentiating characters the distribution of clamp connections and the occurrence of laccase, skeletal hyphae, interlocking hyphae and cuticular cells are used. Seven groups are distinguished which are keyed out separately. About 1100 strains have been tested on the presence of enzymes with 7 different tests. The reactions with α-naphthol (on laccase), p-cresol (on tyrosinase) and pyrogallol and H2O2 (on peroxidase) proved to be useful for taxonomic purposes. The taxonomic position of some species much alike in culture but classified in different groups has been discussed. Hapalopilus rutilans, H, croceus, Tyromyces amarus, T. fissilis, Poria salmonicolor and P. mutans are closely related and should not be placed in three different genera. Globifomes graveolens, Haploporus cytisinus and Trametes robiniophila are closer to Ganoderma than several other species classified in the Ganodermataceae. The separation of Laricifomes officinalis from Fomitopsis and of Buglossoporus pulvinus from Piptoporus is supported by cultural characters. Peniophora gigantea seems to be closer to Meruliopsis than to Phanerochaete. Special attention has been paid to the imperfect states encountered in this study.

The black yeasts and allied Hyphomycetes.
Author(s): G.S. de Hoog and E. J. Hermanides-Nijhof
Details: 222pp., paperback, 1977

  1. Rhinocladiella and allied genera G. S. de Hoog, Centraalbureau voor Schimmelcultures, Baarn, with cooperation of P. Hogeweg, Faculty of Biology, University of Utrecht, Utrecht, H. L. C. Meuzelaar, FOM-Institute for Atomic and Molecular Physics, Amsterdam, and A. C. M. Weijman, Centraalbureau voor Schimmelcultures, Baarn. SUMMARY Characters of numerous strains of Rhinocladiella-like fungi, cultivated under standard conditions, are scored on a datamatrix, comprising 106 attributes. Two groups, viz. fungi or states with sympodial conidiogenesis and the ones with percurrent conidiogenesis, are processed taxometrically. Of both, a dendrogram, and a map of two optimal characters is given, and the differences are discussed. A method is developed for a priori weighting of characters. The thus gained weights of 17 attributes are compared with the automatic weights of the same. Approaches of numerical and classical methods are compared, and diagrams of relationships within and outside the groups studied are presented. Chemical "finger-prints" by means of pyrolysis-mass spectrometry are made of a sample of the concerned organisms; the results are given in non-linear maps. Distinction of groups using this method, is largely based on the presence or absence of rhamnose, and on the chitin-content, as is proved by gas-liquid chromatography. In the descriptive part 9 genera are recognized, two of which are new and two are validated; in all, they contain 37 species or form-species, and 5 varieties. 11 new species are described, two of which are validated, and 20 new combinations and a new name are proposed.
  2. Aureobasidium and allied genera E. J. Hermanides-Nijhof Centraalbureau voor Schimmelcultures, Baarn SUMMARY Aureobasidium Viala & Boyer is characterized by synchronous conidium production on hyaline conidiogenous cells. Five generic names, including Kabatiella Bubák, are listed as synonymous; 14 species and one variety are recognized. Species of Hormonema Lager-berg & Melin produce conidia basipetally from hyaline or dark conidiogenous cells. The majority are cultural states of dothideaceous Ascomycetes; the four described form-species being very similar. The monotypic genus Sarcinomyces Lindner is redescribed to accomodate Cladosporium werneckii Horta.
  3. Survey of the black yeasts and allied fungi G.S. de Hoog and E. J. Hermanides-Nijhof Centraalbureau voor Schimmelcultures, Baarn SUMMARY All accepted genera described in the first two parts of this study, and a number of related genera, are keyed out below. In addition, an annotated checklist of relevant generic, specific and subspecific names is given.

Order Chloridium and some other Dematiaceous Hyphomycetes growing on decaying wood.
Details: 99pp., paperback, 1976
Price: € 20,-

Phialidic species described in Chloridium are revised, described from the natural substrate and/or cultures and connected with perfect states wherever possible. The correct name of the type species of the genus is Chloridium virescens (Pers. ex Pers.) comb. nov. (basionym Dematium virescens Pers.), and the connection with Chaetosphaeria vermicularioides (Sacc. & Roum.) comb. nov. (syn. Eriosphaeria vermicularioides Sacc. & Roum.) has been established. C. chlamydosporis (van Beyma) Hughes and C. caudigerum (Höhn.) Hughes are considered as varieties of C. virescens. These three taxa constitute the section Chloridium which is characterized by phialides with multiple conidiogenous loci active within the collarette. Section Gongromeriza (Preuss) comb. nov. has phialides with a single basipetal sequence of conidia formed within a collarette, in section Psilobotrys (Sacc.) comb. nov. the phialides are constricted at the tip to a narrow collarette and mostly proliferate sympodially. Sect. Gongromeriza contains nine species (incl. C. pachytrachelum, C. phaeosporum, C. matsushimae and C. preussii spp. nov.) of which four are connected with Chaetosphaeria perfect states. Sect. Psilobotrys contains two species, Chaetosphaeria innumera Berk. & Br. ex Tul. (with C. botryoideum (Corda) Hughes var. botryoideum and C. botryoideum var. minutum (Sacc.) comb. nov. as conidial states), and Chaetosphaeria f. fusispora sp. nov. (with C. cylindrosporum st. nov. as its conidial state). Twenty–five other dematiaceous phialidic genera with simple or little branched (but not penicillate) conidiophores are keyed out and five considered in detail. Cylindrotrichum oligospermum (Corda) Bonord. is close to Chloridium sect. Psilobotrys, but has two–celled conidia formed on polyphialides and sterile setae; C. hennebertii sp. nov. has similar conidiophores, slightly shorter conidia and no sterile setae; C. zignoëllae (Höhn.) comb. nov., the presumptive conidial state of Chaetosphaeria abietis (Höhn.) comb. nov. (syn. Zignoëlla abietis Höhn.) and Cylindrotrichum clavatum sp. nov. do not proliferate sympodially and have no sterile setae. Exochalara gen. nov. is described to accomodate Chalara longissima Grove and Catenularia guadalcanalensis Matsushima with large, catenulate, one–celled conidia. Smaller species with usually discrete, thin–walled phialides and catenulate conidia are accomodated in Phialophora sect. Catenulatae sect. nov., viz. Lasiosphaeria hirsuta (Fr.) Ces. & De Not. with Phialophora lasiosphaeriae st. nov., P. clavispora, P. oxyspora, P. olivacea, P. phaeophora, P. brachyconia, P. hyalina and P. brevicollaris spp. nov. and P. rhodogena (Mangenot) comb. nov. (syn. Scopulariopsis rhodogena Mangenot). The very similar Chalara state of Ceratocystis autographa Bakshi and Chalara microchona sp. nov. as well as the conidial state of Cryptendoxyla hypophloia Malloch & Cain are included for comparison. Four species (one new) and three new varieties of Gonytrichum are keyed out: G. mirabile sp. nov., G. caesium var. subglobosum and var. chloridioides and G. chlamydosporium var. simile vars. nov. The perfect state of G. chlamydosporium is Chaetosphaeria chloroconia sp. nov. Verticillium cyclosporum (Grove) Mason & Hughes and V. tenuissimum Corda are accomodated in the new genus Phaeostalagmus and described from pure culture. Single new species are described in both Codinaea and Fusichalara. [p. 2]

Order On Thielavia and some similar genera of Ascomycetes.
Author: J. A. VON ARX:
Details: 32pp., paperback, 1975
Price: € 10,-

The genus Thielavia is restricted to Pyrenomycetes characterized by non-ostiolate ascomata with a wall of textura epidermoidea and ascospores with a single distinct germ pore; 18 species are recognized. The genus Chaetomidium is maintained for 6 species having ascomata with a pseudo-parenchymatous wall, covered with characteristic hairs, and limoniform ascospores with a single germ pore. The new genus Melanocarpus is introduced for Myriococcum albomyces Cooney & Emerson, a thermophilic fungus with dark, usually smooth, pseudoparenchymatous ascomata, and ovoid-oblate ascospores with a single distinct germ pore. Four species characterized by ascospores with two germ pores, one at each end, and by the formation of a Chrysosporium conidial state are classified in the genus Corynascus. A fungus with light ascomata covered with dark hyphae and having ellipsoidal ascospores with two prominent germ pores is described as type of tbe new genus Corynascella. Two further new species are described in the genera Thielavia and Apodus. Species with one-celled ascospores with a germ slit are classified in the genera Coniochaetidium and Ephemeroascus. Identification keys and descriptions of the genera are given.

Order The genera Blastobotrys, Sporothrix, Calcarisporium and Calcarisporiella gen.
Author: J. A. VON ARX:
Details: 119pp., paperback, 1974
Price: € 15,-

The genus Blastobotrys v. Klopotek, comprising only one species, is described. The Ascomycete genus Ceratocystis Ellis & Halst. is divided into two separate genera, mainly on account of the morphology of the conidial states: Ceratocystis sensu str. comprises species with Chalara, Chalaropsis and Thielaviopsis conidial states, whereas the majority of species of Ceratocystis auctt. has Sporothrix, Verticicladiellaand Graphium states and is classified in Ophiostoma H. & P. Syd. Four new combinations in Ophiostoma are proposed. The concept of Sporothrix Hektoen & Perkins ex Nicot & Mariat is enlarged considerably. The presence of more or less differentiated conidiogenous cells, conspicuous denticles, and one-celled, hyaline conidia are regarded as diagnostic characteristics. The genus comprises 24 species; most of them are described and depicted. Six species are described as new, and 3 new combinations are proposed; 13 are conidial states of Ophiostoma. One species is excluded from Sporothrix and redescribed in Nodulisporium. A new genus, Calcarisporiella, is described. It can be recognized by the peculiar shape of the conidiogenous cells. Calcarisporium Preuss is restricted to one species, which can be distinguished by erect, verticillate conidiophores and determinate conidiogenous cells. A list of doubtful and excluded species of Calcarisporium is provided

Paecilomyces and some allied Hyphomycetes
Author: R.A. Samson
Details: 119 pp., paperback, 1974

The genus Paecilomyces (type species: P. variotii Bainier) is monographed and redefined. The delimitation of the genus and its relationship to other genera are discussed; the perfect states belong to Byssochlamys Westl., Talaromyces C. R. Benjamin and Thermoascus Miehe. A key to the described genera and some relatives is given. The morphological characters of Paecilomyces are described; a subdivision into two sections is proposed: In the Sect. Paecilomyces some mesophilic to thermophilic species are accomodated with yellow-brown to brown colonies; several species are accompanied by a perfect state. Mesophilic species with white or other bright colonies are accomodated in the new Sect. Isarioidea; among them are several entomogenous taxa. 31species are keyed out, described and illustrated. The descriptions are mainly based on their morphological characters in pure culture. Paecilomyces aerugineus, P. ghanensis, P. ramosus, P. coleopterorum, P. reniformis and P. niphetodes are described as new species. New combinations for 9 species, originally described in Isaria, Spicaria, Verticillium, Penicillium and Cylindrodendrum are proposed. The genus Mariannaea Arnaud is re-introduced and validated. Penicillium elegans Corda is transferred to this genus; a new variety punicea of this species and a new species M. camptospora are described and illustrated. The genus Nomuraea Maublanc is retained for two entomogenous species, Spicaria rileyi (Farlow) Charles and Isaria atypicola Yasuda. Paecilomyces berolinensis Oláh & Ackermann and P. herbarum Brown & Smith are accomodated in the genus Septofusidium W. Gams. The concept of this genus is briefly discussed. The new genus Gabarnaudia Samson & W. Gams is proposed to accomodate Oospora betae Delacr. and the conidial state of Sphaeronaemella fimicola Marchal. Gabarnaudia tholispora Arnaud ex Samson & W. Gams and G. humicola Samson & W. Gams (ascigerous state: Sphaeronaemella humicola Samson & W. Gams) are described as new species. Doubtful and excluded species originally described in Paecilomyces and Spicaria are listed and two new combinations, Verticillium subfasciculatum (Petch) Samson & W. Gams (= Oospora subfasciculata Petch) and Scopulariopsis parva (Brown & Smith) Samson (= Paecilomyces parvus Brown & Smith) are proposed.

Details: 55pp., paperback, 1973
Price: € 12,-

Species concept and nomenclature of Phoma and Ascochyta species described by Wollenweber & Hochapfel (1936) are reconsidered by means of a comparative study of literature data, original material and numerous fresh isolates. Their sixteen species have been reduced to thirteen: Phoma betae, P. cava, P. destructiva, P. exigua, P. fimeti, P. glomerata, P. lyopersici, P. macrostoma, P. pomorum, P. putaminum, Ascochyta fabae, A. pisi and Stagonospora samarorum. The synonymy, differentiating diagnostic criteria and host relations of these species are discussed, tabulated and illustrated. Asteromella bellunensis (Mart.), Myxofusicoccum pyrinum (Fr.) and Stagonospora populi (Delacr.) are proposed as new combinations.

Order The genus Talaromyces. Studies on Talaromyces and related genera II.
Author(s): A. C. STOLK and R. A. SAMSON:
Details: 65pp., paperback, 1972
Price: € 12,-

The genus Talaromyces is re-defined. It is restricted to species producing asci in chains. The genus is divided into 4 sections, Talaromyces, Emersonii, Thermophila and Purpurea, wich are primarily based on their conidial states. Descriptions, figures and scanning electron micrographs are given of the species belonging to the genus. The species, transferred by Benjamin and Udagawa from the imperfect genus Penicillium to the perfect genus Talaromyces are validated by providing latin diagnoses. Two species of Gymnoascus, G. flavus Klöcker and G. luteus Sacc. and three species of Arachniotus, A. trachyspermus Shear, A. intermedius Apinis and A. purpureus Müller & Pacha-Aue are transferred to Talaromyces. Two new species, T. byssochlamydoides and T. udagawae, and two new varieties, T. flavus var. macrosporus and T. helicus var. major are described. A key to the genera with Paecilomyces or Penicillium conidial states and to the sections of Talaromyces is given. Species are keyed out in each section and in an additional key based on ascospore characters. A new series of Penicillium, the Penicillium cylindrosporum-series is proposed

Order The genera Beauveria, Isaria, Tritirachium and Acrodontium gen.
Author: G. S. DE HOOG:
Details: 41pp., paperback, 1972
Price: € 10,-

The genus Beauveria Vuill. is restricted to three species, of which descriptions and figures are provided: B. bassiana, B. brongniartii and B. alba. The genus Isaria Fr. is described with two species, I. felina and I. orthopterorum. The species formerly placed in Tritirachium Limber are arranged in two genera: Tritirachium, based on T. dependens, characterized by the zig-zag shape of the fertile portions of the conidiogenous cells and the absence of distinct denticles, and Acrodontium gen. nov., based on Chloridium crateriforme van Beyma, characterized by the straight, denticulate fertile portions of the conidiogenous cells. Descriptions and figures are presented of two species of Tritirachium and seven species of Acrodontium. In the latter genus two sections are distinguished: in section Acrodontium the conidia are formed on solitary conidiogenous cells, in section Grisea, based on Tritirachium heimii (Saccas) Langer. var. griseum Fassatiová, compound erect or suberect conidiophores are present which are mostly stiff and pigmented. A list of doubtful and excluded species is given.
