A new subspecies of Mycenastrum corium from colorado.

During field work in Colorado an unusual form of Mycenastrum corium with a deep rusty red to reddish orange gleba was found. The species exists worldwide and lacks a previous description of the gleba at maturity other than olive brown, brown to purple brown. A subspecies is proposed for this unusual population found in an area where normal populations with the typical glebal color are found.
