LICHALP

Lecidea sphaerella Hedl.

Lichenised. Poorly known taxon.

Substrate: lignum

Altitudinal distribution: montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)

Note: a species of unclear relationship, with a very thin, greenish-white to greyish thallus, brownish to blackish-red (pale in the shade), hemispherical to subglobose apothecia, a reddish to brownish hypothecium (and therefore unlikely to represent a Lecania), with some intermixed 1-septate ascospores; on bark of various trees and on wood; overall distribution boreal to temperate-montane, with a few uncertain records from the Eastern Alps (Austria).
