LICHALP

Pertusaria pulvereosulphurata Harm.

Lichenised. Poorly known taxon.

Substrate: bark

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: the type material recalls a yellowish morph of Loxospora elatina, but the chemistry is different (atranorin and unknown substances); likely to belong to a genus other than Pertusaria; on bark of deciduous trees in Western Europe; most records from the Alps are in need of re-investigation.
