Thallus foliose-lobate, closely attached in neat ± regular rosettes, 0.5-4 cm diam., without a marginal prothallus, in sandy soil among mosses. Lobes cuneate-flabellate, 0.5-2 mm wide, contiguous or imbricate, margins rounded to ± incised, slightly thickened, appearing ± placodioid, somewhat gnarled-glomerulate when encircling moss stems. Upper surface pale grey-fawn to ± olivaceous, matt, often fissured from centre to margins, smooth or ± plicate-ridged, without isidia, pruina or soredia. Lower surface whitish, closely intermingled with substratum, without rhizines. Apothecia sessile, closely appressed, disc plane or subconvex, 0.3-0.7 mm diam., dark red-brown, matt, epruinose, margins persistent, rarely excluded, somewhat flexuous, concolorous or slightly darker than disc. Ascospores simple, ellipsoid, thin-walled, smooth, 12-14 × 4-5 µm.
