Pseudopericoniella Videira & Crous, in Videira et al., Stud. Mycol. 87: 374 (2017).

Index Fungorum number: IF 10064; Facesoffungi number: FoF 06853, 2 morphological species (Species Fungorum 2022), 1 species with molecular data.

Saprobic on host. Sexual morph: Unknown. Asexual morph: Mycelium composed of submerged hyaline hyphae, smooth and thin-walled, and aerial hyphae sub hyaline, afterwards becoming dark brown, smooth and thick-walled. Conidiophores arising from creeping aerial hyphae, erect, dark brown at the base, paler towards the apex, thick-walled, septate, branched in the upper part. Conidiogenous cells integrated, terminal and intercalary, sub hyaline, later becoming pale brown, cylindrical, proliferating sympodially, forming a short rachis with conidiogenous loci darkened, slightly thickened and protruding. Conidia solitary, pale olivaceous, smooth, obovoid, ellipsoidal, pyriform to clavate, cylindrical, base long obconicaly truncate and rounded apex, straight to mildly curved, aseptate or septate, sometimes constricted at the septa, with a hilum slightly thickened and darkened (adapted from Videira et al. 2017).


Type species: Pseudopericoniella levispora (Arzanlou, W. Gams & Crous) Videira & Crous


Notes: Pseudopericoniella can be distinguished from Periconiella in having darker and longer conidia. Pseudopericoniella levispora clustered in a distinct clade from other Periconiella species (Videira et al. 2017). Pseudopericoniella is a well-supported distinct genus in Mycosphaerellaceae. Molecular markers available for Pseudopericoniella include LSU, ITS and RPB2.
