Saprobic on wood. Sexual morph: Subiculum composed of numerous, brown to dark brown, branched, septate hyphae, with dichotomously branched, rounded ends. Ascomata scattered or gregarious, superficial, sitting in a subiculum, carbonaceous, brown to black, globose to subglobose, the apex collapsing when dry, tuberculate, glabrous, lacking ostioles, with a central, conical Quellkörper at apex. Peridium outer layer composed of carbonaceous, black tissue; inner layer composed of membranaceous, 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, pedicellate, apex rounded, without apical ring, evanescent. Ascospores bi-seriate to overlapping, hyaline, ellipsoidal to fusiform, aseptate, smooth-walled, guttulate, with a filiform appendage at each end and usually recurved at opposite sides. Asexual morph: Undetermined (adapted from Petrak 1952).
Notes – The monotypic Biciliospora was introduced by Petrak (1952) for B. velutina and initially placed in Coronophorales. Subsequently, this genus was assigned in Coronophoraceae and even accepted as a synonym of Nitschkia (Müller & von Arx 1973, Nannfeldt 1975, Subramanian & Sekar 1990). However, molecular data of Biciliospora revealed that this genus nested in Scortechiniaceae (Mugambi & Huhndorf 2010). In this study, Biciliospora is sister to Scortechiniella (85%ML/1.00BY) in Scortechiniaceae.
Type species: Biciliospora velutina Petr., Sydowia 6(5-6): 429 (1952).
Other accepted species: Species Fungorum – search Biciliospora.
