Rep. N.Y. St. Mus. 45: 83. 1892.
Common Name: none

Mycena strobilinoides can be distinguished by its brilliant orange cap and stipe with orange-marginate gills. Mycena oregonensis is similar but smaller with more yellow coloration and lacks marginate gills. Atheniella aurantiidisca is also similar but has pale yellowish white gills without a deeply pigmented margin and a more yellow stipe. Both Mycena oregonensis and Atheniella aurantiidisca have inamyloid spores and non-spinulose cystidia, features that indicate they are not closely related to Mycena strobilinoides. The closely related Mycena aurantiomarginata also has orange gills with darker orange edges, but this species has a cap with dark brown to brownish orange disc, a more brownish orange stipe, and occurs along the coast at lower elevations.
