Fusiformispora

Fusiformispora Phukhams. & K.D. Hyde, in Phukhamsakda et al., Fungal Diversity: 10.1007/s13225-020-00448-4, [8] (2020).

 Index Fungorum number: IF 557106; Facesoffungi number: FoF 07242, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.

Saprobic on decaying wood or herbaceous plant material in terrestrial habitats. Sexual morph: Ascomata on surface of the host, covered by a pseudoclypeus, visible as black spots, solitary, scattered, uniloculate, obpyriform to compressed globose, coriaceous, brown to dark brown, ostiolate. Ostioles central, brown to dark brown, papillate. Peridium multilayered, cells of textura angularis, inner layers comprising thin, hyaline cells. Hamathecium composed of dense, filiform, branched, transversely septate, trabecular pseudoparaphyses anastomosing above asci. Asci 8-spored, bitunicate, fissitunicate, thick-walled, cylindric-clavate, apically rounded, short, with a furcate pedicel, with ocular chamber. Ascospores biseriate, partially overlapping, broad fusiform, tapering towards the acute ends, hyaline, with guttules in each cell, constricted at the septa, smooth-walled, with a thin mucilaginous sheath. Asexual morph: Unknown (adapted from Phukhamsakda et al. 2020).

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

Notes: Fusiformispora resembles Amniculicola in ascospores features but differ from the latter in ascomatal and asci characters and habitat. Amniculicola has an aquatic lifestyle while Fusiformispora is from a terrestrial habitat. Fusiformispora is morphologically and phylogenetically a distinct genus in Amniculicolaceae. Molecular markers available for Fusiformispora are ITS, LSU, SSU, RPB2 and TEF-1.
