Desertiserpentica
Desertiserpentica Maharachch., Wanas. & Al-Sadi, in Maharachchikumbura et al., Fungal Diversity: 10.1007/s13225-020-00467-1, [25] (2021).
Index Fungorum number: IF 837555; Facesoffungi number: FoF 09484, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Colonies on substratum superficial, effuse, hairy or velvety, dark brown, grey or black. Mycelium partly superficial, partly immersed, composed of branched, septate, smooth, pale brown hyphae. Sexual morph: Unknown. Asexual morph: Hyphomycetous. Conidiophores macronematous, mononematous, simple, cylindrical, unbranched, smooth, olive-green to brown, septate, without percurrent extensions. Conidiogenous cells monoblastic, integrated, terminal, cylindrical or doliiform, determinate, olive-green to brown. Conidia acrogenous, solitary, flexuous, dry, pale brown to brown, distoseptate, long cylindrical with rounded apex (adapted from Maharachchikumbura et al. 2021).
Type species: Desertiserpentica hydei Maharachch., Wanas. & Al-Sadi
Notes: Desertiserpentica is characterised by macronematous, mononematous, simple, cylindrical conidiophores, monoblastic, integrated, terminal conidiogenous cells and acrogenous, solitary, flexuous, dry, pale brown to brown conidia. Desertiserpentica is closely related to Dimorphiopsis but the latter is characterised by pale to brown, septate, branched hyphae, immersed pycnidia to superficial sporodochia and solitary, pale brown to dark brown, 1-distoseptate conidia (Crous et al. 2013). Desertiserpentica differs from Angustimassarina and Amorosia in that the latter has hyphomycetous asexual morphs. Desertiserpentica is morphologically and phylogenetically a distinct and well-defined genus in Lophiostomataceae. Molecular markers available for Desertiserpentica include ITS, LSU, SSU and TEF-1.
