LICHALP

Dacampia hookeri (Borrer) A. Massal.

Syn.: Biatorina sphaerica A. Massal., Pleospora hookeri (Borrer) Keissl., Verrucaria hookeri Borrer

Non- or doubtfully lichenised.

Substrate: parasitic on other lichens, calciferous soil

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 parasite on Solorina species, especially Solorina bispora, which is occasionally found with early infection stages on humic soil over calcareous substrata, mostly on north-exposed slopes; widespread throughout the Alps.
