Cantharellus guyanensis is a tropical South American species of mushroom-forming fungus in the chanterelle genus (Cantharellus), first described by Camille Montagne from French Guiana in 1854.[2]
It has since also been found in Guyana, Suriname, Venezuela, and Brazil. The fruit bodies have a bright orange cap colour and occur in medium- to large-sized troops. C. guyanensis seems to prefer sand-rich soil and forms ectomycorrhiza with a putatively wide range of host trees and shrubs including Coccoloba, Guapira, and Neea.
