Enchylium substellatum, a new lichen species for Russia
UDC 582.29:581.95(571.53)
Abstract
A description and location of a new lichen species for Russia, Enchylium substellatum, are given. The lichen was collected on fine earth at outcrops of crystalline limestone in the stony steppe on the Olkhon Island (Lake Baikal, west coast), in an area characterized by a wide distribution of island intrazonal mountain steppes. The issues of ecology and distribution of this rare lichen are discussed. It was discovered in the same ecotope with other calciphilous lichens (Heppia solorinoides, Gyalidea asteriscus, Toninia tristis, T. diffracta, Gyalolechia fulgens, Buellia elegans, Phaeorrhiza sareptana var. sphaerocarpa, Bilimbia lobulata, Physconia jacutica, Peltigera rufescens, Mycobilimbia obscurata, Lecanora epibryon, Rinodina roscida), some of which belong to the arctic-alpine element of the flora, some to the desert-steppe element, and most species are mountain xerophytes. Based on an analysis of the World distribution and habitats, it was concluded that Enchylium substellatum is an arctic-high-mountain calciphilous terricolous lichen associated with dry habitats. The distribution of the species is limited to the Holarctic, the range is extremely disjunctive. The species is found in cold mountain steppes, cold mountain deserts and dry arctic deserts.
