Verrucaria monacensis Servít

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: according to Breuss (see Nimis 2016), this species was described on the basis of a sample collected on calcareous pebbles in a scree slope near München, and identified by F. Arnold as Amphoridium dolomiticum (=Verrucaria dolomitica), from which it differs in several important characters; the species also resembles Verrucaria muralis, differing in the rimose thallus. Beside the type collection (the original station is probably lost) the species was reported by Sbarbaro (see Nimis 1993: 754) from Piedmont; since Sbarbaro was in close scientific contact with Servít, it is probable that the latter had identified the Italian samples, which constitute the only record from the Alps.
