With its large stature, reddish-purple cap and contrasting yellow gills, Tricholomopsis rutilans is one of our most handsome mushrooms. It fruits in conifer woods, but is infrequent in some years making finds all the more noteworthy. Despite its inviting appearance, Tricholomopsis rutilans has no redeeming culinary value.
