Paraleptospora

Paraleptospora Mapook & K.D. Hyde, in Mapook et al., Fungal Diversity 101: 75 (2020).

Index Fungorum number: IF 557347; Facesoffungi number: FoF 07810, 2 morphological species (Species Fungorum 2022), 2 species with molecular data.

Saprobic on dead stems. Sexual morph: Ascomata immersed to semi-immersed, solitary or scattered, gregarious, coriaceous, globose or subglobose to ampulliform, brown to dark brown, appearing as dark spot with red area on host surface. Ostiole short papillate. Peridium several layers, comprising dense, thick-walled, reddish brown to dark brown, pseudoparenchymatous cells, arranged in textura angularis. Hamathecium composed of filiform or broadly filiform to cylindrical, septate, branching, pseudoparaphyses, anastomosing above the asci. Asci 8-spored, bitunicate, fissitunicate, cylindrical to cylindric-subclavate, straight or slightly curved, pedicellate, apically rounded, with an ocular chamber. Ascospores overlapping, 1–3-seriate, hyaline or pale yellow to yellowish brown, cylindric-fusiform, tapering towards narrow the rounded ends, (5–)6–7(–8)-septate, broader at the center and slightly constricted at septa, straight to slightly curved, guttulate, with or without polar appendages. Asexual morph: Unknown (adapted from Mapook et al. 2020).

Type species: Paraleptospora chromolaenae Mapook & K.D. Hyde

Notes: Paraleptospora is characterised by immersed to semi-immersed, globose or subglobose to ampulliform ascomata, cylindrical to cylindric-subclavate asci, and hyaline or pale yellow to yellowish brown, cylindric-fusiform 7(–8)-septate ascospores. Paraleptospora resembles Leptospora in staining the host surface red but these two genera are phylogenetically distinct. The ideal molecular markers to differentiate between species of Paraleptospora are ITS and TEF1. Molecular markers available for Paraleptospora are ITS, LSU, SSU and TEF-1.
