Pyrenula nitidella (Flörke ex Schaer.) Müll. Arg.

Pyrenula nitidella looks like a small form of the more common P. nitida. It is distinguished by smaller perithecia (usually less than 0.3 mm in diameter) projecting from the thallus, i.e. they are not covered by the thallus; and by wider ascospores (more than 8 µm).

The species prefers smooth bark of deciduous trees (mainly hornbeam and ash). It occurs in natural deciduous forests at lower elevations, e. g., in scree and floodplain forests. It is rare in central Europe. In Bohemia, the lichen is currently known only from a couple of localities, but it is more abundant in Moravia, especially in Moravský kras (the Moravian karst) and the Třebíč and Břeclav regions.
