Description: Thallus crustose, episubstratic, rather thick and usually well-evident, granular to subleprose, greenish. Apothecia short-stalked, 0.5-0.6 mm tall, black with a thin whitish pruina which is most abundant on the lower side of capitulum. Stalk 0.07-0.13 mm thick, of moderately sclerotized, dark, anticlinally arranged, irregularly interwoven hyphae. Capitulum lenticular, 0.25-0.4 mm across, with a well-developed, cup-shaped exciple of largely anticlinally arranged, strongly sclerotized hyphae; mazaedium well developed, black; hypothecium medium brown, with a flat upper surface, of intertwined, 2-2.5 µm thick hyphae. Asci clavate, formed singly, dissolving early, with 2-3 seriate ascospores. Ascospores 1-septate, constricted at septum, dark brown, ellipsoid, 12-14(-16) x 4-6 µm, the wall thick, at first with spirally arranged ridges, then coarsely cracked. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; ascomata I- in all parts. Chemistry: thallus with rhizocarpic and usnic acids.

Note: a temperate, probably holarctic species found on rain-sheltered faces of hard siliceous rocks in humid areas; probably more widespread, but never common.
