Spores look like they have a Q around 1.2

Even where cut, days later.

after all this handling…

it still shows no red or yellow staining. it can’t be protecta.

it does look like one of the grisettes with a friable UV though, so at this point, “cecilea group” is our best bet.

Undescribed sp?

No gray gill edges

As well as no gray in the cap, sunlight or not. This cap is brassy brown.

Thanks for the input, I’ll look further!

A. protecta

Still seems to fit Amanita protecta. The color of the cap could be biased by sunlight.

intelligent to add, but, nice pictures and write up!

Anyone know of anything in the PNW

This could be aside from A. cecilae group?

Any further input?

Anything else to scope that could help put a name on this guy?

Spore photo added, more to come

Quick spore shot at 400x, will do more work later.

Spores are round

Will post photos and more info later.

Amanitas from same location:

Here are some Amanita’s from the same spot (within five feet), in the past



Is there a good microscopic way….
By: Tim Sage (NMNR)
2012-05-27 13:01:43 CDT (-0500)

To determine at least which section this belongs to? I can only go to 400×.

yeah, OK, could just be UV pulled up the stipe, mimicing an annulus.

don’t think that it’s a protecta, though, although prob. something in that group. protecta should redden in all parts with age, and i have never seen a protecta with a tawny cap like this one. the dark stipe ornamentation fits, though.

striate margin is not very dramatic, but hey, variability happens.

I will look more closey at it later

And throw it under the scope as well. Thanks for your input.

I don’t

see this as a true annulus, merely remnants of a universal veil. If you google and check other pictures of ceciliae, you’ll find it typical for the species (or species group?).
- and if it had been an annulus, it doesn’t turn grey in A. pantherina, which also should have a persistent volva with a sharp margin.

It bothers me though, that the cap margin isn’t as striate as expected..

By: Debbie Viess (amanitarita)

then it can’t be ceciliae group, although just looking at the very first photo I thought the same thing as you, Irene.

with that annulus though, just a pretty beat up panther type. even panthers, at least here in NA, can have striate cap margins.
