Aleurocystis gloeocystidiata sp. nov. on Polylepis australis in Argentina

Abstract

The new taxon Aleurocystis gloeocystidiata is described, growing on living branchlets of Polylepis australis in Central Argentina. It is characterized by a discoid-cupuloid basidiome, ellipsoid basidiospores 17-24 x 12-15 μm, metuloid cystidia, sulfonegative gloeocystidia, clamped, non-gelatinized generative hyphae, and encrusted skeletocystidia that are present in the context, form the white, hairy margin of the basidiome, and become grayish in Melzer's reagent.
