I think these are in the lab so I will try to get that info tomorrow. Hopefully I’ll get the chance to meet up with you guys sometime this week! We found alot of interesting things last week.

basidia 2-spored or 4-spored?

Agaricus fuscolilacinus (or Collybia fuscolilacina) has 2 spored basidia – what about yours?
and were there clamp connections?

[we found 2 species today, GSMNP, Greenbrier part]

I have access to journal acticles. Thanks for the references and info. KOH on cap was negative. The specimens are dried now and there is barely enough material that I don’t know if this collection will be useful for sequencing, I will look for more in this location though! Btw, are your most recent observations from the MSA conference at Yale? Again, thanks for the info!

Hi Christine,

Nice find!

Did you put KOH on the cap? The color of the reaction can be really useful for ID.
The size and shape of the spores and presence/absence and shape of cheilocystidia are also important.

A few papers can be downloaded for free at the links below:
http://nature.berkeley.edu/...

And if you email me I can send you a bunch more.

Else or Christian would know about all the publications on them.

Most of them in North America are probably undescribed. This looks similar to one I have found in southern NH; but the gills on mine weren’t as lilac when young, (most of them the gills fade or yellow in age)
It’s also similar to one I have seen in Big Sur, CA… I think Else is working on a few from TN/NC???

Thanks Noah!

Are there any keys to Pseudobaeospora? Are there many possibilities for which species this might be?

Edit: very nice, this observation shows the same rhizomorphs coming off the base of the stipe (present but not shown here): http://mushroomobserver.org/24354?q=RrVB
