Strobilurus trullisatus is one of relatively small number of mushrooms in our area that live on conifer cones. It is recognized by a pale-colored cap with pinkish tones, and a yellowish-brown stipe base. Baeospora myosura also grows on Douglas fir cones, but has a somewhat darker cap, much closer gills, and a distinctly hairy stipe base. A related species, Strobilurus occidentalis, occurs on spruce cones. Strobilurus kemptonae is an older name for this mushroom.
