Biatora chrysantha (Zahlbr.) Printzen

This acidophilous forest species usually occurs as a sterile crust. It grows mainly in valleys of headwaters and in well-preserved mountain forests dominated by beech, where it prefers mossy tree bases. It requires a humid and stable microclimate. Based on the frequency of occurrence and preferences for several forest types in the Šumava Mountains, it has been listed among the regionally more frequent lichens indicating natural beech forests (Vondrák & Kubásek 2019). However, it is relatively common also on Sorbus aucuparia in mountain spruce forests (Malíček et al. 2019). Exceptionally, it was reported from shaded moss-covered stones in scree forests. Apart from Šumava, this lichen is relatively rare in the Czech Republic. It has recently been found in most mountain ranges, including the central Brdy Hills.
