I hate the fact that my picture turned out so cruddy (had a tired 3 year old in tow when I found it.)

What’s not evident in the photo is the ‘frosting’ that the top of the pileus has. They’re not your typical A.muscaria warts.

Due to the time of year, and the wart structure on top, I’m still leaning on A.aprica.

“It is a curious mushroom that shares attributes with both muscaria and gemmata; a volva that can be cupped or ringed, and an annulus or skirt (that is often lost).”


An easy way to help tell the difference is to remove some warts. In A. aprica the warts grow into the cap tissue, leaving scars when removed. A. muscaria does not do that, the warts are easily removed without scarring.

Also, this mushroom looks orange to me, not red (not that it is incredibly important).

by definition the subspecies rank entails a geographically disjunct population. subsp. muscaria and subsp. flavivolvata have been shown to only overlap in Alaska so far. generally speaking, all red/orange ‘muscaria’ samples from the northwest continental U.S have been shown to belong to the flavivolvata clade.
More pics of this particular observation would be helpful, especially a cross-section of the cap.

Corrections or confirmations appreciated.
