BOOK REVIEW «DETERMINANT OF LICENS OF THE SAMARA REGION. PART I. FOLIOSE, FRUTICOSE AND SLIMY SPECIES: STUDY GUIDE. SAMARA: SAMARA UNIVERSITY PRESS, 2018. 128 P.: IL.» OF A.G. TSURIKOV AND E.S. KORCHIKOV

In the Samara region to date, there is a need for a closer study of lichen flora. So far, there is no complete list of species of lichens in the region, but only some local territories, often isolated from each other. Although attempts to study this group of organisms have been undertaken for a long time, this issue has not yet been finally resolved. A positive aspect is the publication of the “Identifier of lichens in the Samara region”. In the work of V.G. Tsurikova and E.S. Korchikova presented the original key for determining leafy, bushy and mucus species, accompanied by color photographs that facilitate this determination. The publication also contains a sufficient complete description of lichens (151 species).
