Saprobic, sexual morph: Ascomata: 0.3-1.4 mm high, 0.3-3 mm in diam., solitary or gregarious, cleistothecial, ellipsoid or subglobose, erumpent and finally superficial, rarely partly immersed, seated in the substratum with broad subicles, coriaceous or cartilaginous, variously coloured: cream-yellow, yellow or reddish yellow, amber coloured and corny when dried, wall dissolving irregularly above. Peridium: 32-80 µm thick, 2-layered, pseudoparenchymatous on the outside, prosenchymatous on the inside. Paraphyses: absent. Asci: 27-44 x 18-27 µm in the sporogenous part, 8-16 x 3-5.5 µm in the peduncle, 8-spored, broadly clavate or ellipsoidal, apiculate, pedunculate, unitunicate, thin-walled with thickened apical wall, aphyloclastic, without an apical apparatuse, and deliquescing early; ascogenous hyphae and asci scattered irregularly throughtout the ascomata center between sterile hyphae. Ascospores: 8-16 µm in diam. (excluding appendages), hyaline, subglobose to ovoidal, unicellular, appendaged, containing one large oil globule; 10-25 awl-shaped appendages, 5.5-10 x 1 µm, slender, acuminate, rigid, distributed more or less evenly over the ascospore surface. Asexual morph: Undetermined (Description based on Kohlm.eyer & Kohlmeyer (1979) and Borse et al. (2012)).
