Pseudomassarina
Pseudomassarina Phukhams. & K.D. Hyde, in Phukhamsakda et al., Fungal Diversity: 10.1007/s13225-020-00448-4, [101] (2020).
Index Fungorum number: IF 557097; Facesoffungi number: FoF 07213, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Saprobic on decaying plants in terrestrial habitats. Sexual morph: Ascomata on surface of the host, visible as black spots, immersed, solitary, uniloculate, obpyriform, brown, rough-walled, coriaceous, with apical ostioles. Ostioles central, brown to dark brown, partially carbonaceous, papillate, filled with periphyses. Peridium multilayered, comprising thin-walled, light brown to brown cells of textura angularis, inner layers comprising hyaline cells. Hamathecium of dense, filiform, branched, transverse septa, pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, thick-walled, oblong, apically rounded, short pedicellate, with an ocular chamber. Ascospores biseriate, overlapping, hyaline, broad fusiform, tapering towards the ends, with transverse septum, guttulate, smooth-walled, with mucilaginous sheath. Asexual morph: Unknown (adapted from Phukhamsakda et al. 2020).
Type species: Pseudomassarina clematidis Phukhams, Camporesi & K.D. Hyde
Notes: Pseudomassarina is characterised by immersed, obpyriform ascomata, brown to dark brown ostioles, oblong, apically rounded asci and broad fusiform hyaline ascospores with transverse septum. Pseudomassarina morphologically resembles genera in Lophiostomataceae, Neomassariaceae and Neomassarinaceae in having hyaline, ellipsoid to fusiform, septate ascospores. Pseudomassarina is a distinct lineage in Pleosporales. Molecular markers available for Pseudomassarina include ITS, LSU, SSU, RPB2 and TEF-1.
