Conservation Status: Not of concern

Mycena aurantiidisca is brilliant orange at first, but gradually fades, usually at the edge of the cap first, to yellowish or almost whitish. Typically, specimens are found that are yellowish around the edge and still bright orange in the center. The gills are whitish at first, then become somewhat yellowish, and the stipe is whitish with a yellowish base. M. aurantiidisca is common on needle litter in moist conifer forests, but usually occurs in relatively small numbers. It is very similar to M. adonis (Bulliard: Fries) S. F. Gray and M. amabilissima (Peck) Saccardo (which is considered a synonym of M. adonis by some mycologists), differing primarily in color, as the latter species are brilliant pink before fading.
