Triadelphiaceae Y.Z. Lu, J.K. Liu, Z.L. Luo & K.D. Hyde, Fungal Divers. 99: 555 (2019)
MycoBank number: MB 555668; Index Fungorum number: IF 555668; Facesoffungi number: FoF 05449; 22 species.
Saprobic on decaying wood, or pathogenic on human, or found from the gut of red palm weevils. Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Conidiophores lacking. Conidiogenous cells holoblastic, monoblastic, integrated, flask-shaped, fusiform, cylindrical or clavate, arising from undifferentiated hyphae, hyaline to pale brown, smooth-walled. Conidia acrogenous, solitary, develop one to five forms in distinct species (adapted from Luo et al. 2019).
Type genus – Triadelphia Shearer & J.L. Crane
Notes – Triadelphia is placed in Microascales as genus incertae sedis (Wijayawardene et al. 2017a, 2018a, Lu et al. 2018). Luo et al. (2019) showed that the Triadelphia phylogenetically shares a sister relationship to the Graphiaceae clade with good bootstrap support (98% ML), but Triadelphia taxa are obviously distinct from the species of Graphiaceae in conidial and conidiophore characters. They introduced a new family, Triadelphiaceae, to accommodate Triadelphia based on morphology and phylogeny.
