Bryoplaca tetraspora (Nyl.) Søchting, Frödén & Arup

in Arup & al., Nord. J. Bot., 31: 68, 2013. Basionym: Lecanora tetraspora Nyl. - Acta Soc. Sci. Fenn., 7: 397, 1863.
Synonyms: Blastenia tetraspora (Nyl.) Rehm; Caloplaca oligospora Th. Fr.; Caloplaca tetraspora (Nyl.) H. Olivier
Distribution: N - Frl (Tretiach & Hafellner 2000), TAA, Piem (TSB 33121).
Description: Thallus crustose, grey, thin, continuous to areolate-granulose, mostly poorly evident. Apothecia frequent, biatorine, rounded, sessile, slightly constricted at base, 0.5-1(-1.5) mm across, with a rusty red, at first flat, then rapidly strongly convex, rough-granulose disc, and a thin, smooth, concolorous, finally excluded proper margin. Epithecium orange, K+ red, C+ purple (in section); hymenium and hypothecium colourless. Asci (2-)4-spored, clavate, Teloschistes-type. Ascospores 1-septate, polarilocular, hyaline, ellipsoid, (22-)24-30(-34) x (12-)14-16(-20)µm, the septum 3-5 µm thick. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; apothecia K+ red, C+ purple (in section). Chemistry: thallus without lichen substances; apothecia with chlorinated and unchlorinated anthraquinones (citreorosein, emodinal, emodinic acid, emodin).
Note: a boreal-montane to arctic-alpine, circumpolar species found on bryophytes and plant debris in areas with base-rich or somehow calciferous siliceous substrata, most frequent above treeline; certainly more widespread in the Alps.
