Abstract
The paper contains data about 20 new and rare lichens of the Chuvash Prisurye. 10 lichens are new for the Chuvash Republic, 5 species are new for the Privolzhskaya Upland. The identified lichen species are indicators of old-growth, undisturbed and intact forests that have been preserved in specially protected natural areas. There are 18 species in the National Park Chuvash varmane and 8 species in the State Nature Reserve Prisursky. Geographical coordinates, distribution features in neighboring regions, ecological-substrate and phytocenotic confinement and age status are indicated for each species. The information on the ecology and distribution of rare lichen species is updated. 18 species of lichens (Bryoria nadvornikiana, Br. trichodes, Cetrelia olivetorum, Cresponea chloroconia, Evernia divaricata, Heterodermia speciosa, Leptogium cyanescens, L. saturninum, Nephroma parile, Scytinium subtile, Sc. teretiusculum, Sc. tenuissimum, Usnea dasopoga, Us. florida, Us. subfloridana, Ramalina thrausta, R. sinensis, Xanthomendoza ulophyllodes) are proposed in the new edition of the Red book of the Chuvash Republic with the Status III - rare species. 2 lichen species (Cetraria ericetorum, Lobaria pulmonaria) are classified as category II-vulnerable species, declining in number.
