Distribution:

Description: Thallus minutely fruticose, ecorticate, subgelatinous when wet, homoiomerous, forming up to to 0.5 cm wide and to 4(-5) mm tall coralloid pillows, black when dry, epruinose or bluish-pruinose. Branches subcylindrical, erect, granulose in lower part. Central part of thallus without photobionts, of loose hyphae. Apothecia not known. Photobiont cyanobacterial, chroococcoid (Gloeocapsa), with a few clustered cells (5-7 μm diam.) the peripheral ones surrounded by a blue-violet gelatinous sheath. Spot test: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: a calcicolous species known only in the sterile state (and generic placement therefore uncertain), found on moist limestone rocks in gorges and similar sites with high air humidity; so far only recorded from the Eastern (Austria) and the Western Alps (France); to be looked for in Italy. The name is invalid.
