Habitat for muscaria var. guessowii…

is quite diverse. I find these mushrooms under a wide variety of conifers, and not infrequently in areas where only hardwoods are present. Cap margin of muscaria var. guessowii may be smooth, vaguely striate, or fairly noticeably striate.

As for ratio cap-diameter/stipe-length, not sure what constitutes expected range for muscaria var. guessowii.

I think the key feature in this observation is the basal volval deposit. Quoting from the Amanita website (for muscaria var. guessowii), “The lower stipe and upper bulb are decorated with partial or complete rings of volval material as in the type variety.” The mushroom seen here fits this description. Also, I think the stipe is on the thick side for frostiana.

I have seen this same color scheme…
