Abstract: Antrodiella americana Ryvarden & Gilb., A. faginea Vampola & Pouzar, A. farinaceaVampola & Pouzar, A. foliaceodentata (Nikol.) Gilb. & Ryvarden, and A. incrustans(Berk. & M.A. Curtis ex Cooke) Ryvarden are discussed and illustrated. Antrodiella farinacea and A. incrustans are published as new to Russia; Gloeoporus amorphus (Fr.) Clem. & Shear var. vassilkovii Bondartsev is confirmed as a synonym of the latter. A key to the species of Antrodiella known from European Russia is provided. Distribution and substrates of Gelatoporia subvermispora (Pilát) Niemelä in European Russia are given. Gelatoporia griseoincarnata Spirin & Zmitrovich, spec. nov. is described as a wide-spored sib of G. pannocincta (Romell) Niemelä. Extremely rare Irpex semisupiniformis (Murrill) Saarenoksa & Kotiranta (=Junghuhnia semisupiniforme (Murrill) Ryvarden) is indicated as new to Russia; it is described and illustrated. On Populus suaveolens growing Oxyporus schizoporoides Zmitrovich & Spirin spec. nov. belongs to Oxyporus corticola-complex, but has wider spores than the North-American O. similis (Bres.) Ryvarden. Coriolus epileucus (Fr.) sensu Bondartsev is Pilatoporus ibericus (Melo & Ryvarden) Kotl. & Pouzar, species new to Russia. The genus Porpomyces Jülich is discussed, and two new combinations,Porpomyces albonigrescens (Núñez, Parmasto & Ryvarden) Spirin & Zmitrovich andPorpomyces balaenae (Niemelä) Spirin & Zmitrovich, are proposed. The latter is found in North-West Russia for the first time.
