Pseudogliophragma Phadke & V.G. Rao, Norw. Jl Bot. 27(2): 127 (1980)

Index Fungorum number: IF 9579; Facesoffungi number: FoF 06557, 1 morphological species (Species Fungorum 2021), 1 species with molecular data.

Lichenicolous on host. Sexual morph: Pseudothecia black, usually spherical, rarely pear-shaped, scattered, located on the periphery of the scales of the host or between them, deepened on ½ to completely immersed in tissue or rhizophytes, on the surface only black tips with a rounded outlet. Pseudothecial walls dark brown to brown-black, uniform as in the upper and in the lower parts, consist of 6–8 layers of pseudoparenchymal cells, pigmented amorphously, uniformly in the cell membranes of pseudothecia. Hymenial gelatin from I– to K / I–. Pseudoparaphyses numerous, branched and anastomosing. Asci bitunictae, thickened in the apical parts, with clear "ocular chamber", cylindrical to narrow-club-shaped, with an arrangement of ascospores in one, less often in two rows, I–. Ascospores 2-celled, hyaline, slightly narrowed at the base, without perisporia, the lower cell is slightly narrower than the upper, the tips slightly elongated. Asexual morph: Undetermined (Adapted from Khodosovtsev and Klymenko 2015).

 

Type species: Pseudogliophragma indica Phadke & V.G. Rao

 

Notes: Pseudogliophragma was introduced by Phadke and Rao (1980) with P. indica as type species. Pseudogliophragma is characterized by loosely constructed and frequently frayed synnemata, with a brown stipe and a divergent capitulum with monoblastic conidiogenous cells and deeply constricted phragmoconidia. Pratibha et al. (2015) proposed the Ramaraomyces as the synonym for Pseudogliophragma and provided an epitype and lectotype for the genus. Pseudogliophragma is related to Wiesneriomyces and belongs to the family Wiesneriomycetaceae.
