Hypogymnia austerodes (Nyl.) Räsänen
Ann. Bot. Soc. Zool.-Bot. Fenn. Vanamo, 18, 1: 13, 1943. Basionym: Parmelia austerodes Nyl. - Flora, 64: 537, 1881.
Synonyms: Parmelia farinacea var. obscurascens Bitter; Parmelia obscurata Bitter non auct.; Parmelia obscurata var. isidiata (Lynge) H. Magn.
Description: Thallus foliose, heteromerous, dorsiventral, adpressed, forming more or less regular, up to 5(-8) cm wide rosettes, the lobes contiguous, (0.5-)1-2(-3) mm wide, clearly swollen especially at the tips. Upper surface greenish grey to brown in peripheral parts, often mottled black, somehow glossy, with laminal, diffuse soredia developing from subisidiose, pustulate papillae. Lower surface black, brownish near the margins and at apex, glossy, erhizinate. Upper cortex of tightly packed, more or less anticlinally oriented hyphae, the cell walls with Cetraria-type lichenan; medulla soon becoming hollow, lining the cavity inside the lobes, the ceiling of the cavity white, the floor pale to dark grey; lower cortex dark, paraplectenchymatous. Apothecia extremely rare, lecanorine, sessile, to 6 mm across, with a brown disc and a thin thalline margin. Epithecium brown; hymenium and hypothecium colourless; paraphyses coherent, simple or sparingly branched in upper part. Asci 8-spored, clavate, Lecanora-type. Ascospores 1-celled, hyaline, broadly ellipsoid, 6.5-7.5 x 4.5-5 µm. Photobiont chlorococcoid. Spot tests: upper cortex K+ yellow, C-, KC-, P- or P+ pale yellow, UV-; medulla K-, C-, KC+ orange-red, P-, UV+ pale blue-violet. Chemistry: upper cortex with atranorin and chloroatranorin; medulla with physodic acid (major), 3-hydroxyphysodic acid (accessory), 2'-O-methylphysodic acid (accessory), plus an unknown substance.
Growth form: Foliose, narrow lobed
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
