We present a new generic concept of the genus Chloridium. It is a little-studied group of soil- and wood-inhabiting dematiaceous hyphomycetes that share a rare mode of phialidic conidiogenesis on multiple loci. The multilocus phylogeny demonstrated that the classic concept of Chloridium is polyphyletic, and the original sections are not congeneric. Therefore, we abolished the existing classification and proposed to restore the generic status of Gongromeriza and Psilobotrys. Chloridium is defined as a monophyletic, polythetic genus comprising 37 species distributed in eight sections. Analysis of published metabarcoding data showed that Chloridium is a common soil fungus representing a significant (0.3 %) proportion of sequence reads in environmental samples deposited in the GlobalFungi database. We demonstrated that Chloridium forms species-specific ranges of distribution, which is rarely documented for microscopic soil fungi.
