Recognized by sight: The darker lower stipe appears to be common in C. hortense. The cap when very young also matches, as do the white spores and warm location.

Alan, I had considered that but did not think we were in it’s range; I suspect you are correct.

I’m having a hard time not seeing this as C. molybdites

Perhaps the spore prints of immature specimens are white?

Yes the spore print was white. I did it half on white paper and half on dark paper. I have seen the green C. molybdites spore print before and this definitely is not that. I also checked at the point where the stipe pulled away from the cap and there was no green. We do have Chlorophyllum brunneum that grows nearby; but, the caps are thicker and look very different in the button phase, like a cracked & burnt marshmallow. The edge of the cap also looked very thin in that you could almost see the gills beneath.
