Now that I blow up the pictures, I see them also, David.

It could just be a very thin-capped specimen of something we already “know” in the rubescent group; or it could be something we don’t know about.

If you should find another rubescent taxon like this with a striate cap margin and have the time to dry material, I’d be very interested in more photos and a look at some of the collection.

Very best,

I can see the grooved cap margin on each of the photos showing the cap.

Seems pretty interesting. “False striations” perhaps?

Your first hand experience trumps my comment.

All of the photos are of the smae individual specimen. I took the last photo after sectioning the cap; I was intrigued by how the pileipellis peeled from the context.

The mushroom in most of the images seems to having bruising too reddish…

for brunnescens.

Very best,


Last image depicts a different species…notice the longish grooves on the cap’s…

edge. This will be a species of subgenus Amanita with inamyloid spores. The other images show a species in sect. Validae as has been noted.

Very best,
