Description: Thallus not evident, not lichenized, parasitic on crustose lichens. Apothecia short-stalked, 0.2-0.3 mm high, solitary or in clusters of up to 7-8, the stalk 0.06-0.08 mm thick, black, in central part formed by pale brown to yellowish, mostly periclinally arranged hyphae, in outer part consisting of strongly sclerotized and intertwined hyphae. Capitulum black, hemispherical to lenticular, 0.2-0.3 mm across; mazaedium, absent. Exciple consisting of 2-3 layers of dark aeruginose hyphae; epithecium dark brown; hypothecium pale yellowish brown, of thin-walled cells with an irregular shape. Asci 8-spored, cylindrical, with a thickened apex penetrated by a narrow canal, formed singly, persisting until the spores are mature, with 1-seriately arranged spores. Ascospores 1-septate, brown, ellipsoid, 7-8 x 2.5-4 µm, with a thick, dark septum and a minute, irregular ornamentation. Photobiont absent. Spot tests: all parts of ascocarps K-, C-, KC-, P-, N-. Chemistry: without lichen substances.

Note: beneath overhangs of siliceous rocks, on the thalli of Haematomma ochroleucum and Tephromela grumosa; according to Roux & coll. (2014) it sometimes grows also on Enterographa zonata.
