Who: Daniel B. Wheeler (Tuberale)

No specimen available

Notes:
Previously known as Martellia, Gymnomyces are also related Russula mushrooms and Macowanite, but lack any stipe and are totally dependant on animal mycophagy for spore dispersal. Instead of a stipe, it sometimes has a small often tiny rootlike attachment.

sporocarp has apparently matured in conjunction with dehydrating. Halo of brown to perhaps cinnamon-brown present. If cinnamon-brown, could be Gymnomyces cinnamoneus. Found with 10-15 year old Douglas-fir at about 2500 feet elevation on Larch Mountain, amidst Western hemlock (old-growth within range) and young re-pro Douglas-fir.
