Chromelosporium re-evaluated, with Chromelosporiopsis gen. nov. and Geohypha stat. nov

Chromelosporium-like asexual morphs of the subterraneous Pezizaceae in the /Pachyphlodes clade are not congeneric with the type of Chromelosporium. Some Chromelosporium morphs are of species in the /Pezizaceae clade (the /Peziza clade), and the genus Chromelosporium as it has been defined is polyphyletic. A diagnostic character that distinguishes these two groups is the presence or absence of conidiophore fasciculation. Mononematous conidiophores characterize Chromelosporium and species related to the /Peziza clade. Synnematous conidiophores characterize Pachyphlodes and other asexual species and define the new genus Chromelosporiopsis, to be excluded from Chromelosporium. Hyphelia terrestris, long misapplied to Chromelosporium, is revaluated, lectotypified, redescribed and recombined as Geohypha terrestris.
