LICHALP

Lecidea swartzioidea Nyl.

Syn.: Lecidea arnoldiana Dalla Torre & Sarnth., Lecidea gneissacea Zahlbr., Lecidea jemtlandensis H. Magn., Lecidea lapicida (Ach.) Ach. var. swartzioidea (Nyl.) Nyl., Lecidea lithophiloides Müll. Arg. non Nyl., Lecidea metamorpha Anzi, Lecidea swartzioidea Nyl. var. lithophiloides (Müll. Arg.) Clauzade & Cl. Roux, Lecidea vogesiaca Schaer.

Lichenised.

Substrate: siliceous rocks

Altitudinal range: from the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies) to the nival belt (above the lower limit of perennial snow and glaciers)

Note: a circumpolar, arctic-alpine to boreal-montane lichen of siliceous rocks, most common near and above treeline; closely related to L. lapicida and doubtfully worthy of being separated from it as a distinct species.
