Callistosporium luteo-olivaceum is a species of agaric fungus in the family Callistosporiaceae. It was originally described in 1859 as Agaricus luteo-olivaceus by Miles Joseph Berkeley and Moses Ashley Curtis in 1859. Rolf Singer transferred it to Callistosporium in 1946. The fungus has an extensive synonymy.[1]
The brownish mushroom has caps up to 4.5 centimetres (1+3⁄4 in) wide. The gills are yellowish and close. The stem is 7 cm (2+3⁄4 in) long,[2] fibrillose and hollow, with yellowish tomentum near the base.[3] The spores are colorless, producing a whitish print[2] or a yellow color in ammonia.[3] The species can resemble Tricholomopsis aurea, T. sulfureoides, and Gymnopilus picreus.[2]
Although rare, C. luteo-olivaceum is widely distributed in temperate and tropical areas of Europe and North America.[4] In 2014, it was reported growing in pine forests in Western Himalaya, Pakistan.[5] The species is inedible.[6]
