Saprobic on wood. Sexual morph: Ascomata perithecial, scattered, semi-immersed to superficial, globose to subglobose, collapsing when dry, membranaceous, black, ostiolate, with papilla. Asci 8-spored, unitunicate, cylindrical, pedicellate, apex rounded, evanescent. Ascospores uni-seriate, obovoid to ellipsoidal, hyaline when young, becoming pale brown to brown when mature, smooth-walled, 3-septate, with a germ pore at each end and with tubercules at the middle. Asexual morph: Undetermined (adapted from Schaumann 1972).
Notes: Biconiosporella is characterized by obovoid to ellipsoidal ascospores with tubercules at the middle (Schaumann 1972). Jones et al. (2009) referred this genus to Lasiosphaeriaceae based on morphological observations. We found that its unique ascospores are similar to Stellatospora (Chaetomiaceae). Molecular data for B. corniculate is lacking, therefore, we place Biconiosporella in Sordariales genera incertae sedis pending fresh collection.
