Wiesneriomycetaceae Suetrong, Rungjindamai, Somrith- ipol. & E.B.G. Jones, Phytotaxa 176: 288 (2014).

MycoBank number: MB 550306; Index Fungorum: IF 550306; Facesoffungi number: FoF 06311, 20 species.

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.

Type: Wiesneriomyces Koord.

Notes: Suetrong et al. (2014) introduced Wiesneriomycetaceae as order incertae sedis, based on morphology and molecular phylogenetic inference. Pratibha et al. (2015) placed Wiesneriomycetaceae in Tubeufiales, and included Pseudogliophragma in this family. Santos (2015) included Speiropsis in this family and suggested Pseudogliophragma as a synonym of Wiesneriomyces. Parawiesneriomyces was included in this family by Crous et al. (2016b). Bezerra et al. (2017) introduced Wiesneriomycetales to accommodate Wiesneriomycetaceae based on morphological characteristics and phylogenetic analyses. Liu et al. (2017) assigned Wiesneriomycetales as a synonym of Tubeufiales based on phylogenetic inference and divergence times estimates which estimated as 40 MYA (crown age).
