Basionym: Lecidea leproloma R. Sant., in Moberg: Lichenes Selecti Exsiccati Upsaliensis Fasc. 1 (Nos 1-25): 6 (1986).
Protolog: Thallus parasiticus supra thallum Lecideae pauperculae, areolatus, esorediosus. Areolae planae vel leviter concavae, fuscae, atro-marginatae. Margo thallosporas nigras format. Apothecia rara, adnata, fusca, leviter convexa, margine inconspicuo. Sporae 8nae, ellipsoideae, parvae. Thallus acidum sticticum, acidum norsticticum et acidum cryptosticticum continens.
Thallus: crustose, forming small patches, 3-7 mm, sometimes crusts up to 15 mm across on the saxicolous thallus of Lecidea paupercula, areolate, esorediate; hypothallus indistinct. Areolae flat to slightly concave, smooth, glabrous, yellowish brown to blackish brown, 0.2-0.7 (-1.2) mm across, 0.1-0.4 thick. Each areola surrounded by a 0.1-0.2 mm broad, black margin formed by a rather loose thallospore forming tissue of bluish black, warty, 7-9 cm thick hyphae. Thallospores (1-)2-3-celled, with irregularly arranged rounded, warty, bluish black cells. Apothecia very rare (seen only in one collection from Sweden: Jämtland, R. Santesson no. 26469), adnate, in the middle of areolae, 0.4-0.5 mm diam., margin thin, not prominent. Excipulum brown, pseudoparenchymatous. Hymenium hyaline, 60-75 µm high. Paraphyses simple or with few branches, thick, conglutinate, apices slightly thickened. Asci clavate with an I+ blue wall and tholus, 8-spored. Spores simple, ellipsoid, thin-walled, smooth, 8-11 x 5-7 µm. Pycnidia unknown (Moberg 1986: 6).
Photobiont: unicellular, green algae, 4-11 µm diam.
Chemistry: Thallus C-, K-, Pd-; stictic, norstictic and cryptostictic acid (Moberg 1986: 6).
Ecology: Parasitic on the saxicolous Lecidea paupercula.
