Abstract
|
|
|
|
In this study the ITS1, ITS2 and 5.8S ribosomal DNA sequences from 29 strains of the Genus Inonotus and its related genera were compared with 31 strains obtained from GenBank database. Using the neighbor-joining (NJ) method and most parsimonious analysis the phylogenetic tree was constructed. The hymenochaetales formed no monophyletic group and several non-hymenochaetales appeared as intermingled with the Hymenochaetales. Strains 6, 46, 49, 50, 53, 55 showed no certain affinities within the Hymenochaetales, whereas Inonotus sp. (51) was closely related to Phellinus baumii, and Inonotus sp. (52), and Inonotus glomeratus (10) was related to Phellinus linteus, and Fomes fomentarius (30) was related to Ganoderma lucidum. Inonotus sp. and Phellinus sp. formed no monophyletic groups and a subdivision in the following genera is accepted: Inonotus sp. Phellinus baumii, Phellinus linteus, Phellinus igniarius, Phellinus pini, Hericium erinaceum, Ganoderma lucidum and Sparassis sp. were confirmed and separated genera. The taxonomic status of Inonotus remained uncertain. Eight new combinations are proposed.
