Miriquidica atrofulva (Sommerf.) A.J. Schwab & Rambold

in Rambold & Schwab, Nord. J. Bot., 117: 118, 1990. Basionym: Lecidea atrofulva Sommerf. - Suppl. Fl. Lapp.: 143, 1826.
Synonyms: Lecidea atriuscula H. Magn.
Distribution: N - TAA (Rambold & Schwab 1990).
Description: Thallus crustose, episubstratic, of scattered, yellowish brown to rust-coloured, 0.2-1 mm wide, usually convex areoles arising on a grey to black prothallus, sorediate. Soralia relatively well-delimited, blue-grey to blackish, crateriform to tuberculate. Medulla white, I-. Apothecia very rare, lecideine, 0.2-0.6 mm across, sessile and constricted at base, with a brown-black to black, glossy, epruinose disc and a thin proper margin. Proper exciple dark brown to dark aeruginose green in outer part, colourless within, of radially arranged hyphae with swollen cells; epithecum olive-brown to pale brown; hymenium colourless, 45-65 μm high, I+ blue; paraphyses mainly simple, 1-2 μm thick at mid-level, the apical cells not markedly swollen, with a dark cap, 3-4.5 μm wide; hypothecium colourless. Asci 8-spored, approaching the Lecanora-type, but with a non-amyloid axial mass and without an ocular chamber. Ascospores 1-celled, hyaline, broadly ellipsoid to subglobose, 8-12 x 5-8 μm. Pycnidia black, immersed in the thallus. Conidia thread-like, curved, 18-22 x 0.6-0.9 μm. Photobiont chlorococcoid. Spot tests: thallus and soralia K+ yellow, C-, KC-, P+ yellow (reactions often more evident on and around the soralia). Chemistry: stictic acid (major), cryptostictic and sometimes norstictic acid (minor or traces).
Note: a circum- and bipolar lichen of metal-rich rocks, with optimum near and above treeline; mostly sterile and therefore perhaps overlooked in the Alps, but never common.
Growth form: Crustose
Substrata: rocks
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
