Phialoparvum Giraldo Lopez & Crous

Phialoparvum Giraldo López & Crous Notes. The genus Phialoparvum was introduced by Giraldo and Crous (2019) to place Phialoparvum bifurcatum, which was isolated from soil habitat in Belgium. To date, three species are recognized in MycoBank (Accession date: March 10, 2025) for Phialoparvum. The genus was introduced solely based on the asexual morph and characterized by its erect, originating directly from vegetative hyphae or hyphal ropes, which can be either unbranched or poorly branched conidiophores (Giraldo and Crous 2019). Conidiogenous cell of this genus is enteroblastic, hyaline, mono-, poly-, and adelophialides, subulate to ampulliform while forming conspicuous collarette. Conidia are cylindrical, hyaline, unicellular, smooth-walled, and aggregated in slimy heads (Giraldo et al. 2019).
