Abstract

A new species of Entoloma, E. aldinophilum, is described from the central Guiana Shield region. The species’ combination of features – including medium-sized, tricholomatoid, yellow basidiomata with intrinsically bright yellow trama, isodiametric, 6-angled basidiospores, and occurrence with the endemic ectomycorrhizal tree Aldina insignis (Benth.) Endl. (Fabaceae subfam. Papilionoideae) – is unique among Entoloma species worldwide.
