Notes: Entoloma carneum is recognized by its plano-umbilicate pileus with pinkish and purplish tints in its colouring and cuboid spores. Presence of clamp connections, oleiferous hyphae and brilliant granules in trama as well as the related yellow discoloration of context have not been mentioned in the protologue. The additional examination of the type specimen shows that E. carneum possesses these characteristics, which could develop in varying degrees. Pleurocystidia were not seen although reported in the protologue.
