Eye3 Eyes3
Recognized by sight: A. brunnescens, perhaps? Base of stipe is wide but not split.
Faint yellow stains on part of stem and gills, but not produced by
scratching/rubbing (or any other color) — I think those might be
a parasite beginning to get to it.

The cap was a bit over 3" across. The yellow was visible on part of the
stem (in the 3rd picture, and a small area of the gills, but rubbing/scratching
did not produce any more, that’s why I didn’t really think it was staining.
No staining of any other colors at all.
The base widens abruptly, the 2nd pictures shows that, but I don’t remember it
flaring upward at all. Didn’t save it …

From the fact that a hand is holding the specimen in the first picture. I take it that this was not a small specimen. A large specimen from Missouri probably eliminates A. solaniolens. Could any of the yellow have been bits of volval material? Does the edge of the bulb have a little rim? It seems to me that there is such a rim in the second photo.

There’s no bruising in the big gash in the stem. If the gash had been there a little while, it might be an argument against the mushroom’s being A. brunnescens — since the explosed flesh did not stain brown.
