Gymnopus brassicolens
Mycotaxon 63: 363. 1997.
Common Name: none
For description see Siegel & Schwarz & 'California Mushrooms'.
Scattered to gregarious on leafy debris under hardwoods and conifers, primarily found under redwood (Sequoia sempervirens); fruiting from late fall to winter, uncommon.
Unknown. Foul odor would be a strong deterrent.
Gymnopus brassicolens can be distinguished by a translucent-striate cap, buff-colored adnexed gills, a tapered (often cleft) stipe with a pallid apex and black base, and a strong fetid odor. Similar species in California include Marasmiellus subpruinosus and Marasmiellus villosipes but they lack the strong odor of rotting cabbage or garlic.
