Abstract
Tylopilus orsonianus sp. nov. and Tylopilus eximius (Boletaceae, Basidiomycota) are described for the first time from the Pakaraima Mountains of Guyana. Both boletes occur in forests dominated by ectomycorrhizal trees in the genus Dicymbe (Caesalpiniaceae). A key to Tylopilus species distinguishes those known to occur in Guyana.
