The results of study the lichens tundrae were generalized within the boundaries of the mountain systems of the Northern Asia. Their species composition and fundamental regulations of spatialis distribution were revealed. Arcto-alpine species of the widespread are making basis of the coenoflorae cum lichens, tum plantae vasculares. 11 typi lichens synusiae determinativus structura and variantia of the associations was revealed. Schema reflecting, structuralis and typologicus diversity of lichens tundrae are compiled. Short description of the fundamental associations was led.Key words: high-mountain, lichen tundra, synusiae, structurno-typologicus organization, Northern Asia.
