Pyrenopsis subcooperta Anzi

Atti Soc. Ital. Sci. Nat., 11: 158, 1868.

Synonyms:

Distribution: N - Lomb.

Description: Thallus crustose to microfruticose, brown-black when dry, dark blood-red when wet, consisting of erect, up to 0.5 mm tall, branched, terete lobules densely aggregated into convex, cushion-like areoles. Apothecia very numerous, covering the whole thallus, terminal at the top of branches, black, very small, at first immersed and perithecioid with a pore-like disc, then adnate and with an expanded disc surrounded by a distinct, prominent thalline margin. Epithecium brownish; hymenium colourless, I+ wine-red, hypothecium colourless. Mature asci and spores unknown. Pycnidia immersed at the top of branches. Photobiont cyanobacterial, chroococcoid (Gloeocapsa), the cells single or clustered, surrounded by reddish-violet gelatinous sheaths. Spot tests: all negative. Chemistry: without lichen substances.

Note: on siliceous rocks with a prolonged water seepage after rain; on the whole, a very poorly known species, also reported from France. The type material, from Mt. Sobretta, was overgrowing epilithic mosses on schist, in the alpine belt.
