Synonyms: Acarospora nitrophila var. tiroliensis (H. Magn.) Clauzade & Cl. Roux; Acarospora suzae f. tyroliensis (H. Magn.) Zahlbr.; Acarospora suzae var. tyroliensis H. Magn.
Description: Thallus crustose, episubstratic, areolate, the areolae (developing on an endolithic hypothallus) contiguous, with an uneven surface, 0.5-1(-2) mm wide 0.4-0.5(-1.0) mm thick, irregular in shape, often angular, separated by deep and wide crevices, replicating by division, broadly attached, eventually becoming elevated by a mycelial base. Upper surface dark dull brown, rough, sometimes brownish-grey or white-pruinose; lower surface dark brown. Epicortex c. 10 µm thick; cortex 10-25 µm thick, of round, 3-5 µm wide cells, or with 2-5(-8) µm thick, vertically arranged hyphae, the upper layer consisting of a single layer of cells with reddish brown gel caps, the lower layer hyaline; algal layer continuous, not dense, 50-100 µm thick, most algal cells 10-14 µm wide; medulla snow-white, eventually forming a mycelial base of intricate, thin-walled, 2-5(-8) µm thick hyphae. Apothecia numerous, usually solitary, 0.4-0.6(-1) mm across, immersed or with a slightly elevated parathecial crown, the disc dull brown or black, rough. Proper exciple up to 25 µm wide; epithecium c. 10 µm high, usually lighter brown than the adjoining cortex; hymenium 80-100(-110) µm high, the hymenial gel euamyloid, IKI+ persistently dark blue; paraphyses c. 2 µm thick, the apices in gel caps, up to 3.5 µm wide, the epithecial gel IKI+ dark blue turning red (hemiamyloid); subhymenium c. 20 µm high, IKI+ blue; hypothecium 15-20 µm high. Asci multispored, 45-80 x 14-19 µm. Ascospores 1-celled, hyaline, ellipsoid, 3-5 x 1.5-2(-2.5) µm. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-. Chemistry: unknown, probably without lichen substances.
