Ricasolia amplissima (Scop.) De Not. - cyanomorph
Giorn. Bot. Ital., 2, 1.1: 179, 1846. Basionym: Lichen amplissimus Scop. - Fl. Carniol., 2nd ed., 2: 386, 1772
Synonyms: Dendriscocaulon bolacinum (Ach.) Nyl.; Dendriscocaulon dendroides auct. eur.; Dendriscocaulon umhausense (Auersw.) Degel.; Leptogium bolacinum (Ach.) Nyl.; Polychidium umhausense (Auersw.) Henssen
Description: Thallus small-fruticose, irregularly branched, 1-3 cm tall, consisting of terete to slightly flattened, apically coralloid branches originating from a subterete basal holdfast, forming bush-like cushions with a more or less distinct main stem, blue-grey to brown (darker at apices), often maculate, paler in the shaded interior of the cushions. Outer surface glabrous or sometimes minutely pubescent, with short, moniliform hairs; cortex of 3-4 layers of cells; interior hyphae longitudinally oriented and radiating out into the branches. Apothecia and pycnidia unknown. Photobiont cyanobacterial (Nostoc), radially arranged below the cortex in primary branches, more or less homoiomerous towards apices of secondary coralloid branchlets. Spot tests: all negative. Chemistry: without lichen substances.
