LICHALP

Bacidia biatorina (Körb.) Vain.

Syn.: Bacidia acerina auct. non (Ach.) Arnold, Raphiospora atrosanguinea Ach. var. biatorina Körb.

Lichenised.

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: a rare, oceanic species growing on trunks of mature trees in old woodlands, mostly in Lobarion-communities; probably more widespread in the Alps than the relatively few scattered records suggest.
