Umbilicaria polyphylla (L.) Baumg.
Fl. Lips.: 571, 1790. Basionym: Lichen polyphyllus L. - Sp. Pl., 2: 1150, 1753.
Synonyms: Gyrophora anthracina (Wulfen) Körb.; Gyrophora glabra (Ach.) Ach.; Gyrophora polyphylla (L.) Funck; Umbilicaria anthracina (Wulfen) Hoffm.; Umbilicaria glabra Ach.
Description: Thallus foliose-umbilicate, heteromerous, dorsiventral, attached by a central holdfast, polyphyllous and cushion-forming, rarely monophyllous, 2-4(-10) cm wide, 0.15-0.2(-0.3) mm thick, fragile when dry, irregular in outline, with lacerate, undulate, entire or deeply dissected margins, the edges strongly up-turned, the umbo slightly folded. Upper surface dark brown to almost black, rarely grey-brown, slightly glossy at least in marginal parts, smooth or with poorly evident reticulate wrinkles. Lower surface smooth, even, sooty black, sometimes brown around the umbilicus, without rhizohyphae; thalloconidia usually 6-10-celled, spherical to ellipsoid, smooth, brown to dark brown, 9-28 x 9-24 µm, completely covering the lower surface, except for a brown area around the umbilicus. Upper cortex palisade-plectenchymatous, 10-20 µm thick; medulla white, loose, with air spaces, 50-100 µm thick; lower cortex scleroplectenchymatous, 10-20 µm thick. Apothecia very rare, black, gyrodisc, 0.5-2(-4) mm across. Epithecium brown; hymenium colourless, 60-70 µm high; paraphyses branched, 1.7-2 µm thick at mid-level, the apical cells more or less swollen; hypothecium dark brown to black. Asci 8-spored, clavate, thick-walled, with an amyloid apical dome, Umbilicaria-type. Ascospores 1-celled hyaline, ellipsoid, 12-19 x 4-8 µm. Pycnidia mainly marginal on upper surface, immersed, globose, with a dark brown ostiole. Conidia bacilliform, 4-5.5 x c. 0.6 µm. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-, P-; medulla K-, C+ red, KC+ red, P-. Chemistry: medulla with gyrophoric and umbilicaric acids (major), and lecanoric acid (minor).
