Scutula epiblastematica (Wallr.) Rehm
Rabenhorst's. Krypt.-Fl., 2nd ed. 1.3, 32: 322, 1890 (1896)]. Basionym: Peziza epiblastematica Wallr. - Fl. Crypt. Germ., 2: 464, 1833.
Synonyms: Biatorina epiblastematica (Wallr.) A.L. Sm.; Catillaria epiblastematica (Wallr.) Vain.; Patellaria epiblastematica (Wallr.) Sacc.
Description: Thallus absent, not lichenized, developing inside the thalli of Peltigera-species, causing bleaching of the host tissue and damage to the host photobiont. Apothecia lecideine, 0.1-0.3(-0.5) mm across, aggregated into clusters or rarely scattered, pale to dark brown or finally black, with a flat to slightly convex disc and a usually persistent proper margin. Proper exciple of parallel, radiating, branched and anastomosing, strongly adglutinated hyphae, the outermost rim colourless, pale brown to dark reddish brown, the inner part colourless, greenish brown to red-brown; epithecium discontinuous, with a granular, greenish brown to greenish black pigment; hymenium colourless, 35-60 µm high, the hymenial gel hemiamyloid; paraphyses septate, very sparingly branched and anastomosing, 1.5-3 µm thick at mid-level. the apical cells markedly thickened, up to 7 µm wide; hypothecium colourless to pale brown, of loosely intertwined hyphae. Asci 8-spored, with an amyloid tholus, a diffuse non-amyloid apical cushion, and an outer amyloid wall layer. Ascospores (0-)1(-3)-septate, hyaline, ellipsoid to narrowly ellipsoid, 8.5–12.5 x 3–4.5 µm, thin-walled, without a perispore. Pycnidia globose, subimmersed to sessile. Microconidia hyaline, cylindrical to shortly filiform, often slightly curved, (4-)5-8(-9) x (0.5-)1-1.5 µm; mesoconidia cylindrical to falcate, (5-)6-8(-9) x (1.5-)2-2.5 µm. Photobiont absent. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: thallus without lichen substances; apothecia with different pigments.
