Phylogenetic relationships in the gymnopoid and marasmioid fungi (Basidiomycetes, euagarics clade).
Three distinct lineages of gymnopoid and marasmioid fungi are recognized in parsimony and Bayesian analyses of nLSU rDNA sequences. One lineage contains the genera Lentinula, Rhodocollybia, Tetrapyrgos, a resurrected and redefined Mycetinis, and two unresolved clades designated /marasmiellus and /gymnopus. /marasmiellus includes the type species of Marasmiellus and is dominated by members of Gymnopus sect. Vestipedes. /gymnopus includes the type species of Gymnopus, Micromphale and Setulipes, and members of Gymnopus sect. Levipedes. A second lineage includes the genera Marasmius s.s. and Crinipellis and represents a redefined /marasmiaceae. A third lineage includes the genera Cylindrobasidium, Flammulina, Gloiocephala, Physalacria, Strobilurus, Xerula and Marasmius sect. Epiphylli and represents /physalacriaceae. One new combination in Rhodocollybia and four new combinations in Mycetinis are proposed. A discussion of the taxonomic implications resulting from the phylogenetic reconstruction is presented.
