Notes: I found these under maple & hickory in a pile of composted grass clippings. Some are pretty big, at about 6" circumference cap by approximately the same height. Delicate (breaks easily) and smells very earthy.
Alan Rockefeller’s comments are as follows:
I have heard rumors that Chlorophyllum brunneum could be found in the east, and it looks like those rumors are true. Please document your rare find by posting these pics on mushroomobserver.org. This does not look quite like the west coast Chlorophyllum brunneum due to the brownish stipe and small scales on the cap, so perhaps a new species or something closer to Chlorophyllum hortense. Very cool in any case, you might want to to dry this collection so an expert can study it.
I have samples which I’m attempting to dry if anyone would be interested in studying.

By “marginate” I mean the top of the bulb is in the form of a “gutter” around the stipe base. In this case, the rim of the “gutter” is not particularly even. So maybe it’s best to describe as “abruptly bulbous”.
Certianly not a trait I have seen on C. rhacopus, which is a common late-season mushroom in my area, generally in conifer needle duff.
I found C. brunneum in NJ three years ago — see obs 111433. It was also IDed by Alan as such. Mine had very scaly caps and prominently abrupt and marginate bulbs, as shown in the pix. It’s weird I found a rare one, but still looking to find C. rhacodes which is supposedly very common in the East…
The bulbs in this obs are very bulbous but not particularly marginate.
the description of C. brunneum, and comparing with C. rhacodes.
Looks like the ones seen here have the abruptly bulbous marginate stipe base, which strongly favors brunneus over rhacodes. An interesting find for NE NA.
Thanks for your reply. Initially when I removed the cap to print it, the cross section of the stipe itself became pretty ruddy in color. However when I sliced the stipe lengthwise, there wasn’t much of a change in color. I’ve added a photo of the stipe sliced lengthwise, and the stipe base looked a bit darker than the rest.
inside a sliced stipe base?
