Heppia lutosa (Ach.) Nyl.

Syn. Meth. Lich., 2: 45, 1863. Basionym: Collema lutosum Ach. - Syn. Meth. Lich.: 309, 1814.
Synonyms: Collema sanguinolentum (Kremp.) Stizenb.; Heppia atlantica Gyeln.
Distribution: N - VG, , Lig. C - Tosc, Sar. S - Cal (Puntillo 2011), Si (Cataldo & Minissale 2015).
Description: Thallus crustose-granulose to subsquamulose, dark brown to almost black when dry, greenish, translucent and slightly gelatinous when wet, of 0.1-1.2 mm wide granules/squamules. Squamules up to 200 µm thick, irregular in outline, homoiomerous, often concave when young,. Upper cortex absent; medulla with mainly anticlinally arranged hyphae. Apothecia one to several per squamule, to 1.5 mm across, with a dark red, at first urceolate, then flat to convex disc. Proper exciple 20-60 µm thick; hymenium colourless, 115-150 µm high, K/I+ blue, then slowly violet-brown; paraphyses mostly simple, lax, distinctly thickened above; subhymenium colourless, 20-35 µm high. Asci 8-spored, cylindrical to obovoid, prototunicate, thin-walled, the wall I+ intensely blue. Ascospores 1-celled, hyaline, ellipsoid to fusiform, 14-18(-26) x (4.5-)6-10.5 µm. Pycnidia immersed. Conidia fusiform, 2.5-3.5 x 1-1.5 µm. Photobiont cyanobacterial (Scytonema-like). Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: a mainly Mediterranean-Atlantic lichen found on more or less calciferous soil in dry grasslands below the montane belt; it was often confused, in the older literature, with H. adglutinata, which is bound to upland areas. Earlier records from the Alps are assigned to H. adglutinata.
Growth form: Squamulose
Substrata: soil, terricolous mosses, and plant debris
Photobiont: cyanobacteria, filamentous (e.g. Nostoc, Scytonema)
Reproductive strategy: mainly sexual
Subcontinental: restricted to areas with a dry-subcontinental climate (e.g. dry Alpine valleys, parts of Mediterranean Italy)
