NOTEWORTHY POLYPORES OF PUSHKIN CITY NEAR THE SAINT PETERSBURG (RUSSIA), THE RESERVE OF OLD-GROWTH TREES. 1. TRAMETES SUAVEOLENS

The paper opens a series focused on noteworthy polypores associated presumable with old-growth broadleaf trees in the Pushkin (Tsarskoye Selo) ensemble near St. Petersburg. Some nemoral species complexes are reserved here due to protection of old-growth trees over this area. The species in focus of the present paper is Trametes suaveolens (Polyporaceae, Agaricomycetes), the species with rather uneven taxonomical history. The basionym initially was applied to another fragrant polypore, and its nomenclature was stabilized rather recently, after its neotypification. This is a rare species associated presumable with large willow trees. In some countries (Britain, Montenegro, Finland, Estonia, some regions of Russia) this species is protected. Four habitats of this protected on St. Petersburg species were revealed in the Pushkin city. All these are documented and an enlarged morphological and ecological description of T. suaveolens is given. A new form T. suaveolens f. dorsalis was described.
