Recent taxonomic discoveries suggest a host-symbiont co-migration of <i>Russula</i> subsect. <i>Castanopsidum</i> with <i>Fagaceae</i> in the Americas.

ABSTRACT: Three members of ectomycorrhizal fungi belonging to Russula subsection Castanopsidum are described from neotropical montane forests dominated by species of Fagaceae in Panama and Colombia. Russula esperanzae sp. nov. from Colombia differs in the field from other members of the subsection by slender longitudinally striated red stipes as well as characteristics of spores and basidia. Russula atroamethystina subsp. atroamethystina, originally described from Costa Rica, is reported for the first time from Panama. Closely related and morphologically similar Colombian collections are described as R. atroamethystina subsp. guacahayoensis subsp. nov. and differ from the typical subspecies by longer hymenial cystidia as well as molecular seque
