Sordariomycetes families incertae sedis


Acrodictyaceae J.W. Xia & X.G. Zhang

Index Fungorum number: IF818894; Facesoffungi number: FoF06600; 25 species.

Saprobic on terrestrial or freshwater habitats. Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Colonies on natural substrate effuse, hairy or velvety, yellowish brown to black. Mycelia immersed, composed of pale brown, septate, branched hyphae. Conidiophores macronematous, mononematous, erect, cylindrical, greenish brown to brown, septate, mostly unbranched, straight or broadly curved, thick-walled. Conidiogenous cells monoblastic, integrated, terminal, cylindrical, greenish brown to brown, thick-walled. Conidia acrogenous, solitary, dry, greenish brown to dark brown, obovoid to pyriform, muriform, deeply constricted at septa; conidial secession schizolytic (adapted from Xia et al. 2017).

Type genus: Acrodictys M.B. Ellis

Notes: Xia et al. (2017) studied acrodictys-like species and established Acrodictyaceae based on molecular data. Acrodictyaceae is a monotypic family containing the type genus Acrodictys. Acrodictyaceae species are characterized by macronematous, mostly unbranched conidiophores and obovoid to pyriform, muriform conidia. Sexual morphs in this family have not been reported.
