Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus)
Note: a species with adpressed to imbricate, small squamules (to 0.6 mm across) with crenulate to sublobate margins, relatively small ascospores (less than 40 µm long), and globose to broadly ellipsoid hymenial algal cells; based on a type from Croatia and showing a southern distribution in Europe; in the Alps it is very rare, at low elevations.
