Syn.: Rinodina mucronatula H. Magn.
Lichenised.
Substrate: lignum, , living mosses, plant debris, calciferous rocks, intermediate rocks (such as calciferous schists)
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: on terricolous mosses and plant debris in open grasslands, over more or less calciferous or otherwise basic to neutral substrata, in sunny, dry, non-eutrophicated situations; perhaps more widespread in the Alps, but overlooked, or confused with other species.
