Sporocadaceae, a family of coelomycetous fungi with appendage-bearing conidia

Species of Sporocadaceae are endophytic, plant pathogenic or saprobic, and associated with a wide range of host plants. Recent molecular studies that have attempted to address familial and generic boundaries of fungi belonging to Sporocadaceae were based on a limited number of samples and DNA loci. The taxonomy of this group of fungi is therefore still not fully resolved. The aim of the present study is to provide a natural classification for the Sporocadaceae based on multi-locus phylogenetic analyses, using LSU, ITS, tef-1α tub2 and rpb2 loci, in combination with morphological data. A total of 30 well-supported monophyletic clades in Sporocadaceae are recognised, representing 23 known and seven new genera. Typifications are proposed for the type species of five genera (Diploceras, Discosia, Monochaetia, Sporocadus and Truncatella) to stabilise the application of these names. Furthermore, Neotruncatella and Dyrithiopsis are synonymised under Hymenopleella, and the generic circumscriptions of Diploceras, Disaeta, Hymenopleella, Monochaetia, Morinia, Pseudopestalotiopsis, Sarcostroma, Seimatosporium, Synnemapestaloides and Truncatella are emended. A total of 51 new species, one nomina nova and 15 combinations are introduced.
