LICHALP

Lecania cyrtellina (Nyl.) Sandst.

Syn.: Lecanora cyrtellina Nyl., Lecidea cyrtellina (Nyl.) Lettau

Lichenised.

Substrate: bark

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) 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 species recalling L. cyrtella, but most ascospores only up to 3 µm wide, occasionally accompanied by macroconidiomata containing simple to 1-septate, falcate macroconidia; on base-rich bark of broad-leaved trees in the shade of old-growth forests; widespread in Europe, NW Africa and North America, as well as in the Alps, but not common, regionally perhaps overlooked.
