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 (Thambugala et al. 2015; Bao et al. 2019c). Asexual morph: Undetermined.

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 2003b). Three strains of B. japonica collected in Japan clustered in a separated clade with Lophiostoma (Thambugala et al. 2015; Bao et al. 2019c). Bao et al. (2019c) found this species from freshwater in China.

 

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

Other accepted species: Species Fungorum – search Lophiostoma.
