Habitat: Narrow mountain gorge, near a stream, locally flat terrain, calcareous ground with some cretaceous clastic rock (flysh) inclusions, broadleaf trees and thickets and high bushes, humid and cold place, in shadow, no sun during most of the year; partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 430 m (1.400 feet), alpine phytogeographical region.

Substratum: dead fallen Corylus avellana branch, not in contact with ground, about 5 cm (2 inch) in diameter,

Comments: Photographed in wet conditions. On the same branch Plicaturopsis crispa, Hypoxylon fuscum, Graphis scripta and Fungi sp. causing distinct red staining of the wood (oac 586). Possibly pyrenomycetes? Sillia ferruginea or Cryptospora corylina or Massariosphaeria rubicunda or ?? (personal communication with Gerhard Koller). Interestingly, the same situation was fond in my first observation of Tectella patellaris (see observation 84928). Fruitbodies growing in groups, more than 30 of them on the same branch; fruitbodies in different stage of development from fairly old to still very young; pileus diameter 5 – 25 mm (1/5 to 1 inch), SP white.
