Chroogomphus ochraceus

Cap: 2-12 cm wide; convex, occasionally with a central point; smooth; slimy when fresh and young, but often dry and shiny or silky when collected; color ranging from yellowish to orangish, reddish, purplish red, or reddish brown--usually darker with maturity.

Gills: Running down the stem; distant or nearly so; pale yellowish at first, becoming grayish cinnamon and finally blackish as the spores mature.

Stem: 3.5-18 cm long; up to 2.5 cm wide; tapering to base; yellowish to pale orangish; sometimes with scattered orangish to reddish fibers (but not densely felty-scaly); often with a wispy ring zone from the collapsed partial veil.
