Distribution:

Description: Thallus crustose, thinly episubstratic, nodulose-verrucose, consisting of 1-5 mm wide, rounded to irregularly shaped, greenish grey warts separated by fine cracks, forming large, often more than 9 cm wide patches with markedly thinner margins, sorediate. Soralia developing from the warts, orbicular, finally often convex, up to 5 mm across, with 20-70 µm thick soredia which finally give rise to coralloid, isidia-like outgrowths. Cortex paraplectenchymatous, 25-40 µm thick; algal layer 50-130 µm thick, the algae usually arranged in vertical rows; medulla white, compact, I-. Apothecia unknown. Pycnidia black, immersed at the apex of the warts, with a widely gaping ostiole. Conidia hyaline, thread-like, straight or the longest ones very slightly curved, (14-)18-23 x c. 1 µm. Photobiont chlorococcoid. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: on periodically submerged rocks and boulders along Alpine streams; known from a few localities in the Eastern Alps (Austria), to be looked for in the Italian Alps.

Growth form: Crustose

Substrata: rocks

Photobiont: green algae other than Trentepohlia

Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)

Periodically submerged (e.g. in creeks)
