Here we describe Cryptogamic Russian Information System (CRIS), a web service cataloguing the biodiversity of cryptogams: cyanobacteria, fungi (including lichens), and bryophytes. CRIS incorporates a wide spectrum of data types, allowing for greater ease of use. It is possible to print the labels for herbarium collections, to input literature references, media files, etc., using CRIS which has a flexible interface and specific technical abilities. Currently, CRIS contains ~ 90,000 herbarium records, including 67,861 records of bryophytes, 12,486 records of lichens and 3,800 records of cyanobacteria. Data analysis of the different taxonomic groups is provided below. Perspectives and directions for the future development of CRIS are discussed.

July, mean water is in August. Soil profile is shallow and typical for the high Arctic. Soil cover is patterned; most part of soils has developed on topography that has been shaped by cryoplanation, on materials disturbed by sloping processes and erosion. Climate of the area is determined by the influence of several ocean currents, one of them, branch of the Gulf Stream, is of particular importance. It is responsible for high air humidity and precipitation. July is the warmest month with average temperature +6.
