Detailed descriptions and illustrations of the fresh and dry basidiomata along with photographs of microscopic elements as spores, capillitium, calcium oxalate crystals, and exo- and endoperidium surfaces are provided. This fungus is typical of the genus in morphology and ecology but differs evidently from every known species. This new species can be easily distinguished by the red-violet (to magenta) exoperidium and the lilac endoperidium. Specimens were collected on wet soil composed by a superficial layer of ca. 5 cm leaf litter and 15 cm of particulate and melanized lignocellulosic material (pH 6.5) under Eugenia uruguayensis and Nectandra sp.
