We studied the easternmost part of the Caucasus, Dagestan, a region neglected by lichenologists in the past, but with recent lichenological activity. We provide here a checklist of 85 species of Teloschistaceae, 39 of them new to Dagestan from our field work in 2015, and four species new to Russia (Athallia nesodes, Caloplaca emilii, Caloplaca xerica and Gyalolechia epiphyta).
