not bicolor.

I’d call it laccata and not bother about all the varieties :-)
However, this key
http://www.fieldmuseum.org/...

is very interesting, because the most common american species (described by Peck) seems to be laccata var. pallidifolia. According to “Funga Nordica” it’s far more common here too than var. laccata. Var. pallidifolia has more globose spores with a Q-value of 1-1.15, var. laccata 1.2-1.3. (this also according to Jan Vesterholt in “Funga Nordica”)
I have to check some next season..

Not L. bicolor…

With the white mycelium it isn’t L. bicolor at least, and these are kinda small for that, although that doesn’t matter much, Laccaria is extremely variable in body form and size.

You are looking at the spores, you should try and get photos, and try for a careful spore size, getting the ave. spore size on 15 spores or so.

I was up there in Mendocino this past weekend, and I got a few of those Laccaria which have pale off-white to pallid gills. I might try to get a spore size from these, and see if that means something…

If you keep looking at these Laccaria, you better watch out, you might become the California expert on these…
