Abstract:  The anatomy, distribution, pathology and cultural characters of Phellinus pomaceus (Pers. ex S. F. Gray) Maire are described on the basis of ca. 470 North European specimens. The main anatomical features separating the species from the P. igniarius complex are the subparallel dissepimental hyphae and thin-walled skeletals in the context. P. pomaceus is fairly common in hemiboreal and temperate southern Fennoscandia, but does not extend farther north. In this region, it occurs almost exclusively on Prunus species, mainly P. domestica L., P. cerasus L. and P. spinosa L., but it has been reported only twice from P. padus L., the commonest Prunus species in Fennoscandia. The cultural characters and anatomy show that P. pomaceus is taxonomically homogeneous in N Europe, except perhaps for a form growing on Crataegus.
A lectotype is selected for P. pomaceus, and the taxonomic position of some closely related taxa (Polyporus corni Velen., Fomes pomaceus f. crataegi Baxter, Fomitiporia prunicola Murr.) is shortly discussed.
