Lecidea strasseri Zahlbr.

It is a relatively conspicuous crustose lichen, closely related to the high-mountain species L. berengeriana, with which it is often synonymized (never concerning its occurrence in the Czech Republic). Lecidea strasseri is rather a forest species of less and middle elevated areas with the presence of calcareous substrates. It is usually found on mossy tree bases, typically on oaks, eventually also on detritus, humus and bryophytes growing on the ground or calcareous rocks. Probably, the only report of L. berengeriana published based on Vězda's exsiccate (Vězda 1989), in fact, according to the ecology requirements, relates to the species L. strasseri. The lichen was in the Czech Republic firstly noticed near Šumperk (Paul 1906), shortly after it had been described from Austria. In addition, recent records come from Moravia, from the Vsetín Hills and the Moravský kras (Moravian Karst). Its distribution in the country is still insufficiently known, and it is expected to occur in more localities. Recently, the lichen has been described in detail morphologically based on a material from Fennoscandia and discussed in terms of ecology and general distribution (Svensson et al. 2020).
