Index Fungorum number: IF 820347; MycoBank number: MB 820347Facesoffungi number: FoF 05408; 22 species.

Parasitic or saprobic on wood or leaves. Sexual morph: Undetermined. Asexual morph: Stroma present or absent. Conidiomata sporodochial, scattered, setose. Setae branched or unbranched, brown, septate, straight to flexuous. Conidiophores macronematous, subcylindrical, hyaline to pale brown, septate, densely packed in a palisade. Conidiogenous cells monophialidic, terminal, hyaline to pale brown, cylindrical to lageniform, with a collarette. Conidia cylindrical to oblong, straight or slightly curved, hyaline, aseptate or septate, sometimes guttulate (adapted from Hernández-Restrepo et al. 2017).

Type genusVermiculariopsiella Bender

Notes – Vermiculariopsiellaceae was established by Hernández-Restrepo et al. (2017) to accommodate a well-supported monophyletic clade containing Vermiculariopsiella. The sexual morph of Vermiculariopsiella was linked with Echinosphaeria based on culture studies (Puja et al. 2006, Dhargalkar & Bhat 2009). However, phylogenetic studies, based on LSU and tub2 sequence data, showed that E. canescens, the type species of Echinosphaeria, resides in Helminthosphaeriaceae (Miller et al. 2014). Therefore, it is possible that the asexual morphs of Echinosphaeria were wrongly identified as Vermiculariopsiella. The linkage between Echinosphaeria and Vermiculariopsiella requires further molecular studies to confirm. We regard the sexual morph of Vermiculariopsiella as undetermined.
