A rare, arctic-alpine terricolous species with a markedly thick, light thallus. Its taxonomical status is not clear and just temporary it is classified as a member of the genus Lecidea. The only information on this taxon mentioned in the Catalogue of Lichens of the Czech Republic (Vězda & Liška 1999) relates to an exsiccate documented by A. Vězda (Lich. Sel. Exsic. N. 2309; Vězda 1989). However, considering the low altitude and the type of habitat where it was collected (valley forest near Tišnov), this data probably belongs to the related L. strasseri, which until recently, was not distinguished by most authors. On the other hand, Czarnota (2007) studied a published record of Lecidea assimilata var. irrubata from Petrovy kameny in the Jeseníky Mountains (Stein 1879, as Lecidella assimilata var. irrubata; leg. B. Stein, 1865, WRSL), and he found it to be the species L. berengeriana. This taxon therefore appears legitimately in the list of lichens of the Czech Republic, even though its occurrence has not recently been confirmed.
