Volume 92 of Studies in Mycology (March 2019) is now available.  This issue includes seven research papers that deal with several important genera of fungal plant pathogens. Damm et al. revise the Colletotrichum dracaenophilum, C. magnum and C. orchidearum species complexes, introducing 12 new species. Marin-Felix et al. revise 20 genera of phytopathogenic fungi, introducing 26 new species. Vu et al. release an unprecedented large number of DNA barcodes for Fungi, namely 24 000 DNA barcode sequences of 12 000 ex-type and manually validated filamentous fungal strains of 7 300 accepted species. Furthermore, the optimal identity thresholds to discriminate filamentous fungal species were predicted as 99.6 % for ITS and 99.8 % for LSU. Maryani et al. deal with the complex issue of Panama disease of banana, and formally name 11 new species, introducing Fusarium odoratissimum for what was formally known as Fusarium oxysporum f. sp. cubense (Foc), the causal agent of Fusarium wilt or Panama disease on banana. Fehrer et al. present a phylogenetic study of the prominent ericoid mycorrhizal fungus Rhizoscyphus ericae. Giraldo & Crous treat the Plectosphaerellaceae, and resolve 22 genera in the family, including 12 new genera, 15 new species and 10 new combinations. Liu et al. treat the Sporocadaceae, finally adding DNA sequence data to many genera of appendaged coelomycetes, resolving 23 known and introducing seven new genera and 51 new species.
