Pseudomonodictys
Pseudomonodictys Doilom, Ariyaw., D.J. Bhat & K.D. Hyde, in Ariyawansa et al., Fungal Diversity: 10.1007/s13225-015-0346-5, [63] (2015).
Index Fungorum number: IF 551348; Facesoffungi number: FoF 00906, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Saprobic on dead wood. Sexual morph: Unknown. Asexual morph: Colonies on natural substrate, superficial, scattered, solitary to gregarious, black. Conidiophores semi-macronematous to sometimes macronematous, septate, branched, pale brown to brown. Conidiogenous cells holoblastic, doliform, integrated, terminal or intercalary, indeterminate, pale brown. Conidia dictyosporous, muriform, top-shaped, reddish-brown to dark brown, solitary, with a protruding basal cell; truncate to slightly rounded at base (adapted from Ariyawansa et al. 2015).
Type species: Pseudomonodictys tectonae Doilom, Ariyawansa, D.J. Bhat & K.D. Hyde
Notes: Pseudomonodictys resembles Monodictys in having semi-macronematous, erect or flexuous, unbranched or irregularly branched conidiophores, holoblastic conidiogenous cells and dictyosporous conidia, but the conidia of Pseudomonodictys have granular contents, a feature absent in Monodictys. Pseudomonodictys also resembles some dictyosporous genera such as Acrodictys and Dictyoarthrinium. It differs from Acrodictys in having semi-macronematous conidiophores producing several conidia, whereas in Dictyoarthrinium, the terminal conidiogenous cell of macronematous conidiophores produces a muriform holoblastic conidium. Dictyoarthrinium differs from Pseudomonodictys by its basauxic conidiophores. Phylogenetically, Pseudomonodictys is a distinct genus. Molecular markers available for Pseudomonodictys are ITS, LSU, SSU, TEF-1 and RPB2.
