Saprobic on wood. Sexual morph: Ascomata solitary to gregarious, immersed to erumpent thought the bark of substrate, coriaceous, globose to subglobose, black, with metallic iridescence, the apex collapsing when dry, lacking ostioles, with Quellkörper. Peridium composed of brown to hyaline cells of textura angularis to textura prismatica, Munk pores present. Paraphyses absent. Asci 8-spored, arising from a hyaline placenta-like tissue, radially extending into the locule around the Quellkörper from the base, unitunicate, clavate to cylindrical, apex rounded, apical ring inconspicuous, with long pedicel, evanescent. Ascospores uni- or bi-seriate, hyaline, aseptate, ellipsoidal to reniform, smooth-walled, with a filiform, flagella-like appendage at each end, guttulate. Asexual morph: Undetermined (adapted from Subramanian & Sekar 1990).

Notes – The monotypic Biciliosporina was introduced as a genus in Coronophoraceae and typified by B. karwarensis in having subglobose ascomata, clavate to cylindrical asci and reniform ascospores with a flagella-like appendage at each end (Subramanian & Sekar 1990). Later, this genus was clarified as a member of Nitschkiaceae based on morphology (Eriksson & Hawksworth 1987, Lumbsch & Huhndorf 2010, Maharachchikumbura et al. 2016, Hyde et al. 2020e, Index Fungorum 2021). We found that the ascospores of Biciliosporina are similar to Janannfeldtia, although the latter has polysporous asci.

Type species: Biciliosporina karwarensis Subram. & Sekar, Kavaka 18(1-2): 69 (1993) [1990].
