LICHALP

Sarcogyne coronata Jatta

Syn.: Biatorella coronata (Jatta) Zahlbr.

Lichenised. Poorly known taxon.

Substrate: calciferous rocks

Altitudinal range: from the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: a calcicolous species with an effuse, epilithic, white to yellowish, continuous to somewhat rimulose thallus, initially urceolate, finally sessile apothecia with black discs covered by a bluish-grey pruina, surrounded by a darker, hardly prominent proper margin and a persistent white thalline rim, in section with a black-brown hypothecium, polyspored asci, and oblong to ellipsoid, hyaline ascospores (3-6 × 1.5-2 μm); only known from the type locality in the Eastern Alps (Italy).
