Abstract: A detailed study of the closely related Albatrellus syringae (Parmasto) Pouzar and A. peckianus (Cke.) Niemelä revealed differences in anatomy, which, in addition to those already known, may be of help in species determination. Thus the cutis of the cap, and the tissue structures of the stipe, can help in a more secure discrimination. Both species are saprobic, and A. syringae probably also can act as a root necrotroph. Albatrellus syringae, an expanding taxon in North Europe since the 1960s, has also emerged in southern Europe, in the Russian Far East, and in northern and western North America. Albatrellus peckianus seems to be an American endemism, distributed within the North American hardwood forests including the Great Lake Region. Both species are mapped on a world scale. Some vouchers from other parts of the world, claimed to be of A. peckianus, did not possess the anatomical features specific to it. Although resembling A. peckianus, orA. syringae, they represent taxa unknown to us.
