Aha, that was a fruitfull collecting trip back in 1911!

Same one, perhaps, where Agaricus hondensis was first described by Murrill and Abrams?

Lepiota fuliginescens was also seen at the 2008 MSSF Fungus Fair, no doubt recognized and named by Ms. Vellinga (now Dr. Vellinga, to you!).

Nice to see you kibbitzing on MO, Dimitar. See, it’s not so bad! ;)

La. fuliginescens was described based on collections from La Honda, CA in (25 Nov 1911).

nifty, thanks Else.

La. brunnescens?

Haven’t been following Leucoagaricus lately, but has that been collected out West before? I’d be curious to hear the final verdict. Let us know.

hard to say what this is, really…

since it is neither fall nor spring, and not under sheltering cypress, either. Else’s first suggestion when she saw it today was L. brunnescens. We’ll see what it turns out to be upon further study.

These Leucoagaricus are fairly common in the spring under cypress, but they may also fruit in the late fall too. I have collection ranging from Dec 1 to May 20. The reddening can be quite prominent. The exact name has been a subject of discussion with Else Vellinga.

Some (not this one here) are in the general La. cupresseus group

This one here might be this one

But recently we found something that we thought was known, but it turned out to be new – in all cases take it to Vellinga .

I will let her make the determination, use chemicals, etc.

Might help with the ID. Or ask Else.

just when you think you’ll never see any cool reddening parasol mushrooms…
