Agaricus pinyonensis

I found it only in the MD Agaricus key and, I believe, in an online or printed (can’t remember) key from the NMMS. Someone in New Mexico is responsible for the naming, to be sure.

RE: Douglas
The most fantastic, awe-inspiring, beautiful mushroom hunts I have ever had have taken place in those 6-8 weeks in the mountains above my family’s home in Santa Fe. This little one was found during that particular window.

Not so xeric…

I lived in Santa Fe in my previous life, and it isn’t so xeric in August-Oct. The months before the snows come in, there is a rain/thunder storm pretty much every day. And all the fungus come out in this short season, they are everywhere for 6-8 weeks, and then they aren’t there at all for the rest of the year. Even though, I didn’t find this one, I didn’t look much under Pinyon, I spent most of my time at the high elevations in the pine/spruce/fir/aspen forests. More stuff up there…

nice…did you eat it?

the edible agaricus species are some of my favorites, altho i’ve never seen (or eaten) this one…apparently associated with pinyon pine and juniper (as you noted). prob. not “MR” with pecan shells either, but rather an opportunistic saprobe, seeking suitable shaded habitat.

nice to find cool shrooms in such a xeric environment. I was gonna mention this isn’t supposed to be when they fruit, but then i saw your sighting date, in August.

Mycorrhizal?

As I understand it, A. pinyonensis is a saprobe with a strong host preference for Pinyon, but it is not mycorrhizal with Pinyon. Have I missed results showing otherwise?
