Monodictys S. Hughes, Can. J. Bot. 36: 785 (1958).
Index Fungorum number: IF 8979; Facesoffungi number: FoF 12305, 58 morphological species (Species Fungorum 2022), 10 species with molecular data.
Saprobic on decayed wood. Sexual morph: Unknown. Asexual morph: Hyphomycetous. Colonies dense, dark brown to black, circular, with indefinite margin, numerous, covering upper surface of the wood, often with presence of dense masses of conidia covering the hyphae. Conidiophores micronematous or semi-macronematous, cylindrical, scattered or caespitose, unbranched or rarely loosely branched, straight or flexuous, pale to mid brown or olivaceous brown, smooth. Conidiogenous cells monoblastic, integrated, terminal, percurrent. Conidia solitary, dry, acrogenous, oblong, rounded at the ends, ellipsoidal, obclavate or subspherical, pyriform or clavate, sometimes irregular in shape, dark brown, smooth, verrucose or echinulate, slightly constricted at one or more of the septa.
Type species: Monodictys putredinis (Wallr.) S. Hughes
Notes: Monodictys is characterised by dark brown to black circular colonies, micronematous or semi-macronematous conidiophores, monoblastic, integrated conidiogenous cells and irregular shaped, dark brown conidia. Rao and de Hoog (1986) provided a key to all species of Monodictys. Monodictys is one of numerous genera characterised by a common solitary, aerogenous, simple, brown muriform conidia that frequently have a protuberant basal hilum. The micronematous conidiophores resembles those of Chuppia but the two genera are probably not related. The taxonomic placement of Monodictys is currently unknown and is in Dothideomycetes, genera incertae sedis. Molecular markers available for Monodictys are ITS, LSU, SSU and TEF-1.
