you would’ve seen that i was putting it in the “pediades group” from the start.

funny about your scowl…I am often smiling when I view MO…even when I disagree with what is being said…so my avatar fits too, which was taken while I was happily hunting mushrooms in the field…MO is just the virtual next best thing to being there. IMHO.

vini vidi nomine. (I came, I saw, I named.) ;)

Ok, that’s slightly better

“Agrocybe pediades group” works better, but still. You saw my comments on MT — we need to study these subject better before applying species names, varieties, etc. Otherwise we’re doing disservice to taxonomy and hide the great diversity of our state. If you’re in the “possibly” or “probably” stage of knowledge then pull back and use sp.

This avatar is just me when reading an observation one time. I was in a motel, reading MO on my laptop, sitting across a big mirror.. Then I noticed my sullen face, a reaction to some incongruous id, I forget which one.. Then I photographed myself to capture that candid MO moment.


as objective as anyone arguing taxonomy in a mostly unexamined group…

It’s certainly an Agrocybe, possibly a pediades, probably in pediades group, although in the field it did look a bit different than the normal pediades, hence my hedging to var. platysperma. This site allows kibbitzing and with this discussion I hardly think that future knowledge will be beaten down by a wrongish ID. Maybe you need a happier avatar?? ;)

Academic argument anyway…altho this is a slightly square peg in a round hole, no further ID possible, altho I remember just where I collected it, for any future San Diego hunters who might follow in my footsteps!

Can you objectively make that species determination?

I do not see how one can objectively make that determination without complete study of the specimens. We have more Agrocybe species in reality than on the books. By putting an epithet we mask our lack of knowledge on that genus. I have seen one or two very similar small Agrocybe, which are clearly not pediades.

read your second comment after I posted mine….

back to the future with this name.

it was not saved.

that was my first hit, too, doug…

but then I saw Arora’s variety that seemed to fit better. has the variety been thrown out over the past 25 years since publication?

This name doesn’t seem to exist…

Look at the discussion that Ron had for Agrocybe “platysperma” recently. It looks like there isn’t any publication of the name “Agrocybe pediades var. platysperma”, except for the listing in Arora. It looks to be a typo, and he might have meant Agrocybe platysperma, which looks to be a name created for one collection from California a century or more ago, and not seen again until Ron brought it back.

Except I think the description of Agrocybe pediades is grossly broad enough that you can’t really say the obs. fall outside, they agree just fine.

But you should save these, and get the dried specimens to Ron, he had been looking at Agrocybe recently, and he would probably be interested in comparing these also.
