The Entolomataceae of the Pakaraima Mountains of Guyana 6: ten new species and a new combination in Nolanea

Eleven Nolanea species are described from Guyanese collections. The West African N. acuta comb. nov. is reported for the first time from the Neotropics, and N. alboproxima, N. applanata, N. clavata, N. claviformis, N. concentrica, N. furcata, N. mimiae, N. rava, N. sinuolata, and N. subsulcata are new to science. All of these species occur in tropical rainforests, either in Upper Potaro River Basin in Guyana's Pakaraima Mountains or in the interior lowlands, and are presumed forest litter saprotrophs. Macromorphological, micromorphological, and habitat data and comparisons with similar taxa are provided for each. The genus Nolanea has not been previously reported from Guyana.
