This was on a deciduous tree. The observation date is the last time I saw this mushroom, but the same log produced it from July until past this observation date.

I have 3 other MO observations of mushrooms from different locations that turned blue and had the same similar distinct scent. I feel like all 4 of these finds had distinctly differing macroscopic features, maybe due to habitat, but I like to imagine there is at least more than one species. I did all my observations on a weekend binge, and I think the dates are wrong.

Definately on a Buried hardwood stump in early june (late spring)

habitat/microscopy

The overall aspect (strongly striated margin, squamulose pileus, bluish discoloration) points to the salicinus clade.

Habitat is very important for ID in section Pluteus, was this growing on hardwood or conifer wood?

Microscopical characters are also important for ID (shape and size of spores and cystidia, presence of clamp-connections on pileipellis)

This is probably what used to be called “Pluteus salicinus var. americanus”, but soon enough will be Pluteus americanus. As far as we can tell the true Pluteus salicinus does not occur in North America.

Microscopy is required for the determination of this species. It is a hallucinogenic pluteus species, the presence of mutiloid cysidia could be a feature to check for, also spore size.

Very interesting collection, one of my favorites to see!
