Wiesneriomyces

Wiesneriomyces Koord.

 

Saprobic on different substrates, colonies effuse, consisting of scattered conidiomata. Mycelium immersed. Asexual morph: Conidiomata sporodochial or synnematal, solitary to gregarious, with or without setae. Setae subulate, septate, pigmented, thick-walled, erect, flexuous, arising from basal pseudoparenchymatous stalk or mycelium immersed in the substrate. Conidiophores macronematous, mononematous, penicillate, septate, branched, straight or flexuous, solitary or gregarious. Conidiogenous cells holoblastic, monoblastic, polyblastic, discrete, determinate, terminate, clavate, cylindrical, slightly ampulliform. Conidia solitary to gregarious, catenate, connected by narrow isthmi, fusiform to falcate, cylindrical, subcylindrical, cuneiform, branched, hyaline to slightly pigmented, aseptate. Sexual morph: Undetermined. (Description from Hongsanan et al. 2020)

 

Type species: Wiesneriomyces laurinus (Tassi) P.M. Kirk

 

Notes: Kirk (1984) proposed the new combination, Wiesneriomyces laurinus, based on the holotype of Volutellaria laurina and showed that it was an earlier name for Wiesneriomyces javanicus. No sexual morph has been reported for this genus (Suetrong et al. 2014; Bezerra et al. 2017; Lu et al. 2018). (Notes from Hongsanan et al. 2020)
