Mycol. Progr., 14, 97: 20, 2015
Synonyms: Sticta fuliginosa auct. Ital. non (Hoffm.) Ach.
Description: Thallus foliose, heteromerous, dorsiventral, isidiate, at first appearing as a single, vase- or trumpet-shaped lobe with revolute margins, borne on an up to 1 cm long, robust stipe and thus looking like a young mushroom, later developing several flabellate, irregular or mostly suborbicular, 2-3(-5) cm wide lobes. Lobes simple or 1-2 branched, adnate to ascending, especially when young, imbricate and overlapping, flat to slightly involute, with rounded, obtuse or even truncate (especially in old thalli) ends. Upper surface smooth to weakly scrobiculate (especially in old lobes), dark brown or rarely pale grey, dull or slightly glossy. Isidia abundant, laminal, at first simple and globose or with a flattened top, later forming erect coralloid masses, < 0.2 mm high, concolorous with thallus or darker. Lower surface smooth or scrobiculate, pale orange to brownish, darker towards the center in old thalli, sparsely to densely tomentose, with usually abundant, 0.4-0.6(-1.5) mm wide, round or angular, urceolate, erumpent to prominent, white cyphellae whose membrane is made of a layer of rounded cells (5-9 μm in diam.) with outer side (that in contact with the air) covered with minute, 4-6(-8) papillae measuring 1–2.5 x 1-1.5 μm, which tend to disappear in old thalli. Upper cortex paraplectenchymatous, 25-40 μm thick, usually 2-layered, the upper layer made of a single row of smaller cells, the lower layer of 3-5 rows of larger cells; medulla white, lax, 40-60 µm thick; lower cortex paraplectenchymatous, 30-40 μm thick, made of 3–5 rows of isodiametrical cells; primary tomentum agglutinated in fascicles; secondary tomentum always present (high magnification!), made of free, unbranched < 20 μm long, moniliform hyphae, with budding apices producing individual rounded cells that act as diaspores. Apothecia extremely rare (known from a single specimen from Switzerland), lecanorine, laminal, sessile, c. 1 mm across, with a concave, brown disc and a pale orange margin with whitish hairs. Epithecium orange-brown; hymenium brown to red-brown, 60-90 μm high. Asci 8-spored, cylindrical to clavate, unitunicate, with an amyloid cap in the tholus, Peltigera-type. Ascospores 1-3(-7)-septate, hyaline to dark brown, ellipsoid-fusiform, with smooth walls, 16.4-25 x 6.2-8 μm. Photobiont cyanobacterial ( Nostoc, the cells in compact masses). Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
