Mycena strobilinoides
What You Should Know
Mycena strobilinoides can be distinguished by its brilliant orange cap and stipe with orange-marginate gills. It occurs less commonly elsewhere in northern North America and also in Europe. M. strobilinoides seems to be most common at mid-elevations in the mountains, often in association with pines. Grows scattered to gregarious on conifer needles; uncommon in the Klamath and Cascade Ranges of northern California.
Edibility is unknown, too small to have culinary value.
Other names: Scarlet Fairy Helmet.
