Observation 49830: Macrolepiota Singer

When: 2010-08-07

Collection location: Huachuca Mountains, Cochise Co., Arizona, USA [Click for map]

Who: wbwarner

Specimen available

Fairly common in spots and possibly a new state record. Chlorophyllum molybdites was fruiting at the same time in nearby mountain ranges, but all I saw in the Huachucas was procera, some gigantic (a foot wide and a foot tall).

[admin – Sat Aug 14 01:58:14 +0000 2010]: Changed location name from ‘base of Huachuca Mts, Arizona’ to ‘Base of Huachuca Mountains, Arizona, USA’

At least more edible ones!

I am with you! After seeing Chlorophyllum molybdites fruiting at the same elevation everywhere else across the southern half of AZ at the same time, I was really happy to see the Macrolepidiota sp. Hopefully someone more intrepid than me will confirm its edibility—a “saute, taste & spit test” showed the flavor to be good. And this year, anyway, they were plentiful at the spot.

The world already has enough scarab beetles, what it really needs is more Macrolepiota species!

Didn’t mean to start a controversy, just report a potential new state record…

In response to Else’ suggestion: I personally don’t know that it is not procera (though from your posts it appears not), and besides, I am too busy describing new scarab beetles to worry about the finer points of fungal taxonomy. I am very glad this website exists, however; the quick feedback is certainly welcome!

Isn’t that YOUR job?!

You know, if you have a good collection, know that it is different from real M. procera, what are you waiting for? Why don’t you do your homework and describe it yourself?

Nice rant, you remind me of a friend of mine. Not attacking your ID, just saying. I call them Macrolepiota procera too, when nobody’s looking. Have a nice day.

OK, then: for the splitters, “the US, white spored thing that goes by the misapplied name….”

I guess I should have put “procera” in quotes. The same can be said for the Amanita “caesarea” that grows locally, is well known, yet apparently nameless. Too bad the splitter crowd cannot seem to describe even the well known, edible “species” and leaves them nameless!! Hopefully the gel-slicing gene grinders are not relying solely on some arbitrary genetic distance statistic for such “species” determinations! Spores (like small insects) are carried long distances and show up in far away areas, with the resultant island-like populations diverging slightly via genetic drift and local selection pressures. But, I digress….
