Parabambusicola

Parabambusicola Kaz. Tanaka & K. Hiray., in Tanaka et al., Stud. Mycol. 82: 115 (2015).

 Index Fungorum number: IF 811327; Facesoffungi number: FoF 01727, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.

Saprobic on host. Sexual morph: Ascomata mostly grouped, immersed to erumpent, subglobose in surface view, hemispherical with flattened base in section. Ostiolar neck short papillate, central. Ascomatal wall at the sides composed of pale brown, flattened cells; at the rim, composed of parallel rows of rectangular to polygonal cells. Pseudoparaphyses numerous. Asci broadly cylindrical to clavate, short stalked, 8-spored. Ascospores fusiform, multiseptate, primary septum mostly supramedian, hyaline, smooth, with an entire sheath. Asexual morph: Unknown (adapted from Tanaka et al. 2015).

Type species: Parabambusicola bambusina (Teng) Kaz. Tanaka & K. Hiray.

Notes: Parabambusicola is characterised by mostly grouped, immersed to erumpent ascomata, broadly cylindrical to clavate, short stalked, 8-spored asci and fusiform, multiseptate ascospores. Parabambusicola bambusina previously known as Massarina bambusina was treated as a member of Massarina but not congeneric with the type of the genus, M. eburnea (Tanaka & Harada 2003b). Parabambusicola can be differentiated from Massarina in having hemispherical to depressed globose ascomata enclosed by stromatic tissue and deprived of prominent clypeus, broadly cylindrical asci, and fusiform ascospores with numerous septa. Parabambusicola is phylogenetically distinct and distant from Massarina. Parabambusicola is a well-supported genus in Parabambusicolaceae. Molecular markers available for Parabambusicola are ITS, SSU, LSU and TEF-1.
