K. Vetensk-Acad. Nya Handl., 15: 101, 1794. Basionym: Lichen velleus L. - Sp. Pl., 2: 1150, 1753.
Synonyms: Gyrophora cirrhosa (Hoffm.) Flörke non auct.; Gyrophora vellea (L.) Ach.; Gyrophora vellerea Nyl.; Umbilicaria cirrhosa Hoffm. non auct.; Umbilicaria spodochroa auct. p.p. non Hoffm.
Description: Thallus foliose-umbilicate, heteromerous, dorsiventral, mainly monophyllous, rigid, 4-8(-20) cm wide, 0.2-0.3(-0.4) mm thick, with entire to incised, slightly up- or down-tuned margins, attached by a thick, dark, more or less central holdfast. Upper surface whitish, pale brown to greyish violet, dull, smooth to scabrous, distinctly rimose with dark cracks, slightly raised and with a few trabeculate folds over the umbo. Lower surface brown-grey, except around the base of the rhizinomorphs, which is black due to the thalloconidia, more or less scabrous, with a dense felt of rhizinomorphs except around the umbilicus and in the marginal zone. Rhizinomorphs of two types: black, short, stout and ball-tipped, immixed with others which are pale brown to ivory white, cylindrical, simple or branched. Thalloconidia large, 22-40 x 31-60 µm, multi-septate, 50-300-celled, dark brown to black, irregular, arising both from the lower cortex and in clusters from the tips of rhizinomorphs. Upper cortex palisade-plectenchymatous, 11-30 µm thick; medulla white, dense, 45-130 µm thick; lower cortex brown, scleroplectenchymatous, 20-60 µm thick. Apothecia rare, gyrodisc, black, to 3 mm across. Epithecium black-brown; hymenium colourless; paraphyses mostly simple, with enlarged apical cells; hypothecium brown. Asci 8-spored, clavate, thick-walled, with an amyloid apical dome, Umbilicaria-type. Ascospores 1-celled, hyaline, broadly ellipsoid, 9-12 x 6-8 µm. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-, P-; medulla K-, C+ red, KC+ red, P-. Chemistry: medulla with gyrophoric, lecanoric, hiascic and umbilicaric acids.
