Verrucaria geophila Zahlbr. nom.illeg. non Nyl.

Lichenised.
Substrate: acidic soil (mostly on siliceous substrata)
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: a rare species of slightly calciferous soil in dry Mediterranean grasslands, including those at the base of the Western Alps. The name is illegitimate and would require conservation.
