LICHALP

Lecanora leptacina Sommerf.

Syn.: Lecanora intricata (Ach.) Ach. var. leptacina (Sommerf.) Stizenb.

Lichenised.

Substrate: living mosses,

Altitudinal range: from the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers) to the nival belt (above the lower limit of perennial snow and glaciers)

Note: a probably circumpolar, arctic-alpine lichen found on mosses (Andreaea, Grimmia) and plant debris in sites with a long snow cover above treeline, in areas with siliceous substrata; perhaps more widespread in the Alps, but not common.
