To the 15th Anniversary of Aphyllophoralean Fungi Studiesin the Pinezhsky Nature Reserve: History and New Data
Additional 46 species to the aphyllophoralean fungi biota of the Pinezhsky Reserve are reported. Among them, Ramaria fasciculata is given for the first time in Russia and 7 species are new to the Arkhangelsk Region (Amyloxenasmagrisellum, Antrodiellaserpula, Botryobasidiumcandicans, Brunneoporusminutus, Ceriporiaaurantiocarnescens, Irpexlitschaueri, and Schizophyllumamplum). At present, the total list of aphyllophoralean fungi of the Pinezhsky Reserve includes 377 species, while 29 species are known for the Arkhangelsk Region only from this area. The degree of study of aphyllophoroid fungi on different substrates has been analyzed. The increase in the number of species at the collection points depends on the diversity of woodland conditions (forest types). In the reserve area the specificity of substrates is rather low and more than a quarter of species are recorded once. The Thuring coefficient for the Pinezhsky Reserve area is 72.7%. Within the territory there are 27 species listed in the Red Book of the Arkhangelsk Region, and 40 indicator species are registered, of which 27 are indicators of old-growth and 13 of virgin spruce and pine forests. This proves that the forests of the reserve can be considered especially valuable and unique. The group of aphyllophoralean fungi has been studied quite comprehensively, while data on other groups of macromycetes are still scattered.
