Biappendiculispora Thambug., Kaz. Tanaka & K.D. Hyde

Index Fungorum number: IF551528


Saprobic on dead herbaceous stems or culms of Poaceae or submerged wood. Sexual morph: Ascomata solitary to gregarious, immersed, with papilla erumpent through host surface, reddish brown to black, subglobose, coriaceous, ostiolate. Ostiole variable in shape, central, with a pore-like opening, plugged by gelatinous tissue, made of hyaline, pseudoparenchymatous cells. Peridium composed of a single stratum, with several layers of cells of textura angularis, fusing with the host tissues in outer layer. Pseudoparaphyses numerous, cellular, hypha-like, hyaline, septate, branched. Asci 8-spored, bitunicate, fissitunicate, cylindric-clavate, with short, bulbous pedicel, with an ocular chamber. Ascospores uni- to bi-seriate, fusiform, with acute ends, septate, constricted at the septa, pale yellowish to brown, with hyaline appendages. Asexual morph: Undetermined. (Descriptions from Dong et al. 2020)


Type species: Biappendiculispora japonica Thambug., Wanas., Kaz. Tanaka & K.D. Hyde


Notes: The monotypic genus Biappendiculispora was introduced for B. japonica (Thambugala et al. 2015) which was initially described as Lophiostoma caulium “var. f” (Tanaka and Harada 2003). Three strains of B. japonica collected in Japan clustered in a separated clade with Lophiostoma (Thambugala et al. 2015; Bao et al. 2019; Dong et al. 2020). Bao et al. (2019) found this species from freshwater in China. (Notes from Dong et al. 2020)
