Abstract Based on morphological and phylogenetic investigations, four new species, Clitocella termitophila, Clitopilus velutinus, Rhodocybe dominicana, and Rhodocybe pseudoalutacea, one new variety, Rhodocybe luteocinnamomea var. fulva, and first reports of Clitopilus prunulus, Rhodocybe mellea, and Rhodocybe roseiavellanea are described and illustrated from the island of Hispaniola. Three protein coding genes, RPB2, TEF1, and ATP6, were used to compare taxa and make phylogenetic inferences about novel species and varieties. Where necessary, because of non-availability of these protein coding gene data for every taxon, ITS sequences were used to confirm uniqueness or species similarity for C. velutinus and R. mellea, respectively. This contribution is a result of and based on numerous expeditions in the Dominican Republic by two different groups over a 20-year period that were designed to gather data on macrofungal biodiversity of this region. The new agaric taxa documented here contribute to the limited but growing knowledge on biodiversity of the Entolomataceae (Agaricales) for the Dominican Republic and the island of Hispaniola. Keywords Agaricales . ATP6 . RPB2 . TEF1 . Termite nests . New taxa
Introduction Rhodocybe Maire, Clitopilus (Fr. ex Rabehn.) P. Kumm., Clitopilopsis Maire, Clitocella Kluting, T. J. Baroni & Bergemann, and Rhodophana Kuhner are genera of Entolomataceae that represent a phylogenetic unit currently referred to as the Rhodocybe-Clitopilus clade (Moncalvo et al. 2002; Co-David et al. 2009; Kluting
et al. 2014). The Rhodocybe-Clitopilus clade, with approximately 300 species described so far worldwide, is the smaller of the two monophyletic groups that make up the Entolomataceae, i.e., the Entoloma clade and the Rhodocybe-Clitopilus clade. Members of the RhodocybeClitopilus clade are mainly found as saprotrophs in tropical and/or temperate ecosystems in both hemispheres (Maire 1926; Singer 1947, 1969, 1973; Singer and
