Taxonomy of displaced species of Tubaria.
A taxonomic treatment of vinaceous and reddish species of Tubaria (Agaricales) is presented based on morphology and nucleotide sequences. Accessions from western North America, Europe, Central America, the Caribbean and Australia are compared. Phylogenetic analysis of the 25S rRNA gene and internal transcribed spacer (ITS) regions demonstrates that Tubaria is not monophyletic. However the autonomy of six brown-spored, saprotrophic species-Naucoria vinicolor, Pholiota serrulata, Phaeomarasmius confragosus, Pholiota punicea, Tubaria rufofulva and T. bispora sp. nov.-is affirmed. All six species form a strongly supported monophyletic group that we label section Confragosae in the genus Tubaria. This section is related to T. dispersa, T. albostipitata and numerous representatives of the T. furfuracea complex. Tubaria minima is related to other lineages of dark-spored Agaricales. Taxonomic descriptions, illustrations and a key to confirmed species of section Confragosae are provided. Four new combinations are proposed, and one new species, T. bispora, is described as new from Costa Rica and Martinique. A lectotype is designated for Pholiota serrulata.
