Arthrorhaphis alpina (Schaer.) R. Sant.

An arctic-alpine species, very similar to the common A. citrinella, from which it differs mainly in the presence of calcium oxalate crystals in the medulla, the spore type and the usual absence of soredia. It grows on soil, often calcareous, on open stands in the mountains, usually above the tree line. It parasitises the lichen*Baeomyces rufus* when young, but non-parasitic thalli are commonly found, too. Its European centre of distribution lies in Scandinavia and the Alps. Recent unpublished records in the Czech Republic come from the top parts of the Krkonoše and Hrubý Jeseník Mts. According to a recent revision of the genus, the species probably includes various taxa and requires further studies (Frisch et al. 2022).
