Abstract:  The relationships of the European poroid Hymenochaetales were assessed from an array of 20 characters: 14 morphological and microscopical features of the fruit body, cultural type and nuclear behaviour of the secondary mycelium, extractable styrylpyrone contents of the basidiocarp, electrophoretic protein patterns and type of enzymatic abi lity of the mycelium. Taxonomic information was retrieved in two ways: phenetic and phylogenetic.
As a result, the Hymenochaetales are divided into two suborders, Phaeolinae Fiasson & Niemelä and Hymenochaetinae Fiasson & Niemelä, the former comprising one family (Phaeolaceae Jül.) and the latter three (Hymenochaetaceae Donk, lnonotaceae Fiasson & Niemelä and Phellinaceae Jül.). The following genera are accepted to accommodate the European species which were formerly included in the genera of Inonotus and Phellinus: Inonotus Karst., Inocutis Fiasson & Niemelä (formerly the Inonotus rheades complex), Inonotopsis Parm., Phylloporia Murr. (P. ribis complex), Fomitiporia Murr. (P. robustus complex), Porodaedalea Murr. (P. pini complex), Ochroporus J. Schroet. (P. igniarius complex), Phellinidium (Kotl.) Fiasson & Niemelä (P. ferrugineofuscus and its allies), Phellinus Quél. (P. torulosus), Fuscoporia Murr. (P. ferreus and Its allies), and Fulvifomes Murr. (P. rimosus complex). Within these genera, 23 new combinations of species names are proposed. The concepts of the genera and families are emended, and the affinities of the Hymenochaetales to the other groups of fungi are discussed.
