LICHALP

Lecidea laboriosa Müll. Arg.

Syn.: Lecidea leptoboloides Nyl., Lecidea lithophilopsis Nyl.

Lichenised. Poorly known taxon.

Substrate: siliceous rocks

Altitudinal range: from the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron) 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 still insufficiently known species of L. plana-group with narrower ascospores; on siliceous rocks, usually at high elevations; distribution poorly documented.
