摘要：

Morphological and habitat descriptions, illustrations, and taxonomic commentary of five species of Tylopilus occurring in the Pakaraima Mountains of Guyana, South America, are presented. These fungi occur in forests dominated by ectomycorrhizal trees in the genus Dicymbe (Caesalpiniaceae). Tylopilus potamogeton var, irengensis is described as a new variety, T. rufonigricans and T. exiguus as new species. A new combination is proposed for Boletus vinaceipallidus, which, along with T. ballouii is recorded for the first time in Guyana.
