Abstract

Cosmospora sensu Rossman (Ascomycota, Sordariomycetes, Hypocreales, Nectriaceae) accommodated nectroid fungi with small, reddish, KOH+, smooth, thin-walled, laterally collapsing when dry, non- or weakly stromatic perithecia. Recently, the group was found to be polyphyletic based on molecular data, and has been segregated into multiple genera. Not all Cosmospora-like fungi have been treated systematically. Some of these species include C. vilior and many specimens often labeled as ?Cosmospora sp.? The objectives of this research were to establish the identity of C. vilior through epitypication using a recent collection that agrees with the type specimen in morphology, host and geography, and to determine its phylogenetic position within Cosmospora sensu lato and the Nectriaceae. A multilocus phylogeny was constructed based on six loci (ITS, LSU, rpb1, MCM7, tef1, and tub) to estimate a phylogeny. Results from the phylogenetic analyses indicated that C. vilior forms a monophyletic group with other Cosmopora-like fungi that have an acremonium-like anamorph and that parasitize Eutypa and Eutypella (Ascomycota, Sordariomycetes, Xylariales, Diatrypaceae). The group is phylogenetically distinct from other previously segregated genera. A new genus, Pseudocosmospora is described to accommodate the type species, P. eutypellae, and nine additional species in this clade.
