LICHALP

Verrucaria glauconephela Nyl.

Lichenised. Poorly known taxon.

Substrate: calciferous rocks

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)

Note: closely related to and perhaps a synonym of Parabagliettoa cyanea, with an endolithic thallus indicated by patches of a whitish-greenish colour with a bluish tinge, semi-immersed ascomata (to c. 0.15 mm in diam.), an adpressed involucrellum reaching down about half the perithecium, and ellipsoid ascospores (to c. 15 µm long); on calcareous rocks at low elevations in continental Europe (based on a type from Hungary), with a few records from the Western Alps (France).
