LICHALP

Verrucula coccinearia (Zehetl.) Nav.-Ros. & Cl. Roux

Syn.: Verrucaria coccinearia Zehetl.

Lichenised.

Substrate:

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) 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 rare species with a grey to brown thallus consisting of a few, thin areoles forming small isles (to c. 2 mm in diam.) on the thallus of the host lichen, with subglobose to globose ascospores (to c. 12 µm in diam.); with its host Caloplaca coccinea on limestone, mainly at high elevations; so far known from a few localities in the Alps, but perhaps overlooked.
