Mycena rosea (NL: Heksenschermpje / EN: Rosy bonnet / DE: Rosa Rettich-Helmling / FR: Mycène rose) is a species of mushroom in the Mycenaceae family. First named Agaricus roseus in 1803 by Danish botanist Heinrich Christian Friedrich Schumacher, it was given its present name in 1912 by Gramberg. The cap initially has a convex shape before flattening; its diameter may reach up to 6 cm. The fruit bodies of Mycena rosea contain two red alkaloid pigments that are unique to this species. Named mycenarubin A, and mycenarubin B, these chemicals are related to the so-called damirones that are found in marine sponges. The species appears in autumn in deep leaf litter beneath deciduous trees. This is a poisonous species and should not be collected for food; it contains the dangerous toxin muscarine.
