Myriolecis agardhiana (Ach.) Śliwa, Zhao Xin & Lumbsch subsp. agardhiana var. agardhiana

Syn.: Lecanora agardhiana Ach., Lecanora agardhianoides A. Massal., Lecanora latzelii Zahlbr.
Lichenised.
Substrate: calciferous rocks
Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) 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 widespread holarctic lichen found on horizontal to weakly inclined surfaces of hard limestone and dolomite, with a wide altitudinal range, but with optimum below the subalpine belt; the distinction from other related taxa still needs further study.
