Saprobic on dead stems or submerged wood. Sexual morph: Ascomata scattered or clustered in group, immersed to erumpent, hemispherical with flattened base, ostiolate, with short, central papilla. Peridium composed of pale brown, flattened cells at the sides and parallel rows of rectangular to polygonal cells at the rim. Pseudoparaphyses numerous, cellular, hypha-like, hyaline, septate. Asci 8-spored, bitunicate, broadly cylindrical to clavate, short pedicellate. Ascospores tri-seriate, fusiform, multiseptate, hyaline, smooth, with an entire sheath (Tanaka et al. 2015). Asexual morph: Undetermined.
Notes: Parabambusicola was established to accommodate a known species Massarina bambusina Teng (Teng 1934; Tanaka and Harada 2003c). Both P. bambusina and P. thysanolaenae Goonas. et al. were isolated from dead stems in terrestrial habitats (Teng 1934; Tanaka and Harada 2003c), while our new species P. aquatica was found on submerged wood in freshwater habitats.
Type species: Parabambusicola bambusina (Teng) Kaz. Tanaka & K. Hiray.
Other accepted species: Species Fungorum – search Parabambusicola.
