Tubaria punicea 

It is a rare and beautiful mushroom in the Inocybaceae Family, recognized by a dark-red to reddish-purple cap, vinaceous gills that at maturity become ochre-brown to cinnamon-brown from spore deposit, and a vinaceous, fibrillose-striate stipe.

This species is known only from coastal regions of California, Oregon, and Washington, in the United States; fruiting from late fall to mid-winter.
