ABSTRACT

Polyporoid and lentinoid fungi contain the important producers of substances having immunomodulatory, antitumoral, antiviral, and antihyperlipidemic effects. The discovery of several phylogenetic lines within the lentinoid-polyporoid continuum will help with target metabolomic analysis of species still not studied in pharmacological respects. The purpose of the present work was to increase a resolution in the lentinoid-polyporoid phylogenetic zone by means of selection of both the main representatives of Lentinus-related genera and poorly known/intermediate taxa such as Lentinus suavissimus, Neofavolus spp., and the resupinate part of Polyporus (genera Perenniporia and Pachykytospora) in the context of the basic structure of the Polyporales tree. The molecular phylogeny of highlighting all the polyporoid and lentinoid nodes was reconstructed using nLSU ITS rDNA and TEF datasets. The data obtained from ITS, TEF, and LSU coincide in support of core Polyporaceae of 10 clades corresponded to the generic level and 7 of these (Cerioporus, Cladomeris, Favolus, Lentinus, Neofavolus, Picipes, and Polyporus s.str.) contain generic units characterized by polyporoid or lentinoid morphotypes. The other 2 clades containing lentinoid taxa are outside the core Polyporaceae, namely Panus (Meruliaceae, Polyporales) and Neolentinus (Gloeophyllaceae, Gloeophyllales). A new genus, Picipes, is described and 25 new combinations are proposed.
