Rinodina pyrina (Ach.) Arnold

A minute Rinodina with very inconspicuous thallus and crowded small apothecia. The spores are often slightly curved (i.e., they are not regularly ellipsoid as in other species) and have a thin cell wall, only slightly thickened around the septum (Physconia type).

The lichen grows on twigs and bark of deciduous trees in communities of nitrophilous lichens. It is probably more common in canopies and only rarely colonizes trunks (mainly of younger trees). It might also be found on wood and small steppic shrubs. It is widely distributed in both Europe and the Czech Republic. Here, it is the most common Rinodina species. Its centre of distribution lies at lower and middle elevations, but also expands to the mountains (e.g. the Třístoličník Mt in the Šumava Mts at 1300 m a. s. l.).
