<i>SIDERA TIBETICA</i> (<i>HYMENOCHAETALES</i>, <i>BASIDIOMYCOTA</i>), A NEW SPECIES TO RUSSIA

Abstract

The first findings of recently described polypore fungus Sidera tibetica are revealed in the Caspian lowland forests of the Samursky National Park in the Republic of Dagestan, Russia. Basidiomata collected on Pinus brutia var. eldarica were studied by both light microscopy and molecular methods. Detailed information on new localities and habitats of Sidera tibetica as well as the collection numbers of specimens deposited in the Mycological Herbarium of the Komarov Botanical Institute of RAS (LE) are provided. Two complete sequences of ITS1–5.8S–ITS2 nuclear ribosomal DNA for Caucasian specimens of S. tibetica have been obtained and submitted to the GenBank database. Newly generated sequences are formed a separate well-supported clade in the Maximum Likelihood phylogenetic analysis together with all available ITS nrDNA sequences of S. tibetica originated from Belarussian and Chinese collections including the reference sequence from a holotype.
