Magnicamarosporium
Magnicamarosporium Kaz. Tanaka & K. Hiray., in Tanaka et al., Stud. Mycol. 82: 119 (2015).
Index Fungorum number: IF 811292; Facesoffungi number: FoF 01684, 2 morphological species (Species Fungorum 2022), 2 species with molecular data.
Saprobic on host. Sexual morph: Unknown. Asexual morph: Conidiomata pycnidial, scattered, immersed, depressed globose in section. Ostiolar neck central, papillate to short cylindrical. Paraphyses filamentous, sometimes branched, associated with gelatinous material. Conidiophores absent. Conidiogenous cells holoblastic, cylindrical to doliiform. Conidia subglobose to obovoid, sometimes obpyriform, muriform, dark brown (adapted from Tanaka et al. 2015).
Type species: Magnicamarosporium iriomotense Kaz. Tanaka & K. Hiray.
Notes: Magnicamarosporium is characterised by pycnidial conidiomata, cylindrical to doliiform holoblastic conidiogenous cells and subglobose to obovoid conidia (Tanaka et al. 2015, Phukhamsakda et al. 2017). Magnicamarosporium resembles Camarosporium in having muriform brown conidia but differs in that the former genus has larger conidiomata with a visible ostiole, long paraphyses with mucilaginous coating, and larger conidia (Tanaka et al. 2015). Magnicamarosporium belongs to Sulcatisporaceae while Camarosporium is a member of Pleosporineae (Crous et al. 2015b). Magnicamarosporium is morphologically and phylogenetically a distinct genus in Sulcatisporaceae. Molecular markers available for Magnicamarosporium are ITS, LSU, SSU, RPB2 and TEF-1.
