LICHALP

Micarea elachista (Körb.) Coppins & R. Sant.

Syn.: Bacidia sororians (Nyl.) H. Olivier, Biatora elachista Körb., Biatorina glomerella (Nyl.) Arnold, Catillaria elachista (Körb.) Vain., Catillaria glomerella (Nyl.) Th. Fr., Lecidea poliococca Nyl., Lecidea sororians Nyl., Micarea glomerella (Nyl.) Hedl.

Lichenised.

Substrate: lignum, 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 cool-temperate to circumboreal-montane species with optimum on lignum, more rarely on acid bark, in Castanea-forests, often with Chaenotheca ferruginea; certainly more widespread in the Alps, but much overlooked.
