Walkeromyces Thaung, Trans. Br. mycol. Soc. 66(2): 213 (1976).

Index Fungorum number: IF 10427; Facesoffungi number: FoF 08672, 1 morphological species (Species Fungorum 2022), no molecular data available.

Hyphomycetous, foliicolous, pathogenic. Sexual morph: Unknown. Asexual morph: Stroma, setae and hyphopodia absent. Mycelium superficial, consisting of brown, branched, septate, creeping hyphae. Conidiophores simple or branched, medium brown, arising from superficial mycelium, straight to flexuous, with intergrated terminal conidiogenous cells. Conidiogenous cells polyblastic, terminal, sympodial, with thickened, darkened scars. Conidia dry, solitary, acropleurogenous, straight or curved, obclavate or fusiform or short navicular, septate, smooth, brown, with thickened, darkened hilum (adapted from Thaung et al. 1976).


Type species: Walkeromyces grewiae Thaung.


Notes: Walkeromyces is characterised by superficial, brown mycelium, simple or branched, medium brown conidiophores, polyblastic, terminal, sympodial conidiogenous cells and obclavate or fusiform or short navicular, septate conidia. Walkeromyces has mycovellosiella-like morphology, and has been considered as a synonym of Passalora (Crous and Braun 2003).The placement of Walkeromyces in Mycosphaerellaceae is doubtful. The type species must be re-collected and sequenced for further study.
