Recognized by sight: this is what I was trying for the first time. the old name, Agaricus meleagris, gets changed to Leucoagaricus here on MO. I just shrugged and went, oh no, not another one.

now that’s a whole nuther can ’o (mushroom) worms.

can’t wait for the Kerrigan book to come out, and hopefully settle some of these name issues.

I agree with Debbie

the dark, radially fibrillose cap (and large size) look good for A. moelleri/A. praeclaresquamosus (MD).
But neither of those are western names (and it’s probably not any of the European taxa), so it’d be best to use sensu CA. Or we can just sit tight and wait for Kerrigan’s Agaricus tome..

uh, really?

I dug this up, and observed all features, but alas lost that first photo series. This was a largish Agaricus sp. with a cap heavily ornamented with dark fibrils and scales, with a smooth stipe and pendulous annulus and a small rimmed basal bulb that stained bright yellow at the extreme bottom. It was buried along a path near an oak grove.

It smelled phenolic.

All those details say Agaricus moelerii to me, the Agaricus of many names, and the MDM Arora description confirms it.

What western sp. do YOU believe it to be, Bloodworm?

no pics…but OF COURSE this is an Agaricus…

formerly meleagris and praeclaresquamosus.

when I typed in Agaricus melaeagris, MO changed it to Leucoagaricus melagris. Check it out yourself.

Anyway, apparently there are two mushrooms with the same old name.

No worries, at the time I was both surprised and disgusted at yet another name change, but didn’t have the time to investigate further.
back to reality and phew.

how about some more pics Deb?

Wrong autofill?

Phenol odor and yellowing (and the look of the cap) – did you mean Agaricus in section Xanthodermati?

The cap doesn’t look like this:
