You may have hit it on the head, Moselio. Thank you. I don't notice any
cloven-foot bases, but haven't dug up many. However, they are
_definately_ near A. gemmata which are also fruiting now. I always though
that A. brunnescens was a rather robust species with noticeable
striations on the edges of the cap. These striations are not present on
most of what I am finding. The only other questionable characteristic is
the abundance: there are literally hundreds of specimens: far more
abundant than Helvella lacunosa or Gomphidius sps, which are also fairly
common in the stand. There are also thatcher ant nests up to 3 feet high,
typically fruiting abundantly Macrolepiota rhacoides after the first
heavy fall rains.
Thanks for replying, Moselio. BTW, I have your book In The Company of
Mushrooms, (c, 1997 by Harvard University Press), and have enjoyed your
writing style a lot! Great photos as well. I wish I had your eye for

Maybe that's what's throwing me off. I typically associate A. brunnescens
as rather rare, and mostly from the coast range forests. This is in the
foothills area of the Cascades, near the base of Mt. St. Helens.
Then again, I suppose it could always be a new species.

I haven't noted the brown-bruising reaction either. I'll have to test it
the next time I go looking.

Interesting. But both species at this site are found in near pure stands
of Douglas fir. In fact, the plantation was planted at 10 foot spacings,
and other tree species (including hardwoods or understory deciduous
shrubs) are quite rare.
I can't explain the

I thought the same thing at first, but there are no cobwebby veils, nor
noticeable annulus, nor the typical cortinarious veils even on very
young, barely emergent specimens with gills still not unfolded.
Obviously I need to spend more time making spore prints and drying
specimens for others to identify. Detailed notes and measurements
wouldn't hurt, either. It's just that when I usually find them, I'm
spending most of my time gathering truffles...and attempting to avoid
_all_ forms of Amanita. I guess I'm basically Amanita-phobic, even though
I like finding them and looking at them on the collection table. (Sigh)
