Didysimulans
Didysimulans Tibpromma, Camporesi & K.D. Hyde, in Tibpromma et al., Fungal Diversity 83: 76 (2017).
Index Fungorum number: IF 552770; Faceoffungi number: FoF 2884, 2 morphological species (Species Fungorum, 2022), 2 species with molecular data.
Saprobic on dead stems. Sexual morph: Ascomata immersed, solitary, globose to irregular, conspicuous at the surface, black, with or lacking ostioles. Peridium composed of brown cells arranged in a textura angularis. Hamathecium comprising dense, septate, guttulate pseudoparaphyses. Asci 8-spored, bitunicate, cylindrical, slightly curved, short pedicellate, apically rounded. Ascospores 2-celled, hyaline, 1-septate, guttulate, enlarged at the first cell, constricted at the septum, conical at the ends, lacking a mucilaginous sheath. Asexual morph: Chlamydospores occasionally produced, hyaline to yellow–brown mycelium, in spiral chains.
Type species: Didysimulans mezzanensis Tibpromma, Camporesi & K.D. Hyde
Notes: Didysimulans was introduced by Tibpromma et al. (2017) based on morphology and multigene analysis and typified by D. mezzanensis. Didysimulans can produce chlamydospores in spiral chains and the ascospores differ from other genera such as Leptosphaerulina, Platychora, Monascostroma, Macroventuria and Didymella (Hyde et al., 2013). Didysimulans is morphologically and phylogenetically a distinct and well-defined genus in Didymellaceae.
