spores large, almost squared/rectangular in shape, 8 × 5 microns.

pleurocystidia abundant, horned, in Congo Red.

Specimen dropped off w/Else at UCB yesterday.

thanks Ron.

I finally found it once I opened that paper in a more easily readable form.

The macro does mention that yellow base, and the micro is a good match, too. Nice to have my Pluteus ID question, for a new to me species, answered so quickly!

Timing is all. ;)

in a quick read through your paper (forwarded to me by my hubby), that was the name that popped out to me, too! I couldn’t find a macro description, though. I can also throw it under the scope, but would gladly pass it along to Else if she’d like it. Not mutually exclusive things!

cap surface

the pale colors and the aspect of the cap surface remind me of Pluteus leucoborealis, one of the new species that we just described, but without habitat or microscopical data it is just a guess.

If Else or somebody else can scope and it really is P. leucoborealis it should be relatively easy to ID

it was not collected by me …

just pulled out of the fungal heap due to it being interesting. so … could have been growing on anything, really.

cool photos!

Debbie, do you remember what kind of wood/remnants was this growing on?
