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 .
