The Lichen Genus Rinodina in North America: 142, 2010. Basionym: Buellia notabilis Lynge - Skr. om Svalbard og Ishavet, 81: 121, 1940.

Synonyms: Buellia parvula (H. Mayrhofer & Poelt) H. Mayrhofer & Scheid.; Rinodina parvula H. Mayrhofer & Poelt

Distribution: N - TAA (Nadyeina & al. 2010).

Description: Thallus crustose, episubstratic, forming small patches, greyish-white, ash-grey to grey-brown, somehow glossy, not well delimited, up to 1 mm thick, the areoles usually scattered, up to 1(-1.3) mm broad, angular, sublobate, sometimes developing on a thin, black hypothallus. Apothecia immersed and cryptolecanorine to sessile and lecanorine, contiguous and becoming angular, up to 1 mm across, with a concave to flat, black, scabrid disc, and a thin, crenulate, finally sometimes excluded thalline margin. Thalline exciple (55-)70-90 µm wide laterally when present, the cortex 10-15 µm thick, usually with a 5-20 µm thick epinecral layer; crystals absent in cortex and medulla; proper exciple brownish to brownish-violet in outer part, colourless within, (5-)10-20 µm wide laterally, expanding to (20-)30-50 µm in upper part; epithecium dark brown, K-; hymenium colourless, not inspersed with oil droplets, 90-110 μm high; paraphyses branched in upper part, 1.5-2(-3) μm thick at mid-level, the apical cells 4-6(-7) μm wide; hypothecium colourless, up to 150 μm high. Asci 8-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-septate, slightly constricted at septum, brown, ellipsoid, 13-19 x 7-11.5 μm, Milvina-type, with a verruculose wall, the ontogeny of type A (apical wall thickening after septum formation). Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: on more or less calciferous rocks in upland areas; the species is known also from Austria, Switzerland, France, Slovakia, and Spain, and from North America (Sheard 2010).
