Parasulcatispora

Parasulcatispora Phukhams. & K.D. Hyde, in Phukhamsakda et al., Fungal Diversity: 10.1007/s13225-020-00448-4, [119] (2020).

 Index Fungorum number: IF 557204; Facesoffungi number: FoF 01686, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.

Saprobic on dried stem of herbaceous plants. Sexual morph: Ascomata solitary, gregarious, semi-immersed to erumpent, subglobose to compressed, coriaceous, dark brown to black, ostiolate. Ostioles central, filled with hyaline periphyses. Peridium thin, uniform of flattened cells of textura angularis, thin-walled, cells towards the inside lighter, inner layer composed of thin, hyaline, gelatinous layer. Hamathecium composed of numerous, filamentous, branched, septate, anastomosing, trabeculate pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, cylindrical-clavate to clavate, asymmetric, with furcate pedicel, apically rounded, with an ocular chamber. Ascospores 2-seriateor partially overlapping, broad fusiform, hyaline, tapering towards the ends, 1-euseptate, constricted at the septum, smooth-walled, with guttules in each cell, with mucilaginous sheath. Asexual morph: Unknown (adapted from Phukhamsakda et al. 2020).

Type species: Parasulcatispora clematidis Phukhams. & K.D. Hyde

Notes: Parasulcatispora resembles Sulcatispora in having immersed, subglobose to hemispherical ascomata, short ostiole, trabeculate pseudoparaphyses, and fusiform hyaline, septate ascospores with mucilaginous appendages. Parasulcatispora also resembles Sulcatispora but lacks a pseudo clypeus and has small flattened ascomata with narrower asci and ascospores. Parasulcatispora forms a well-supported distinct genus in Sulcatisporaceae. Molecular markers available for Parasulcatispora are ITS, LSU and TEF-1.
