Thank you, Patrick.

Very best,

It’s the cap color that makes me hesitate to go for pophyria.

Dave, you’re right about the gray partial veil in porphyria sometimes becoming more distinct in age; however, there is gray on the margin (at least) of the ring from early on.

This specimen makes me think a little of a small brunnescens or a light-colored specimen of A. solaniolens.

First four pics remind me of…

A. porphyria, except for the white stipe, and white ring. Not sure about whether the gray tones develop as porphyria matures.

I will split those out

I will split those out into a second observation, and do so with the
samples also.

I hadn’t seen the second half of the pictures. I agree with David’s observation.

The bottom four pictures might show a pink-spored taxon. or a pink-gilled species of Amanita, which exist in sections Vaginatae (not a candidate here because of the membranous partial veil), Caesareae, and Phalloideae.

Whatever grouping is appropriate for the entity in the second four pix, it is not sect. Validae, which I still think is appropriate for the first four pix.

Very best,

Rod

The two photos of stipe base…

appear to show different specimens. The one photo shows a splitting bulb. The other photo appears to show a volva with free limb.

It looks like there is a true bulb at the stipe base.

Possibly it is splitting as in A. brunnescens. This suggests the species could be in Amanita sect. Validae.
