the orginial description…

Is why nobody could even put a name on this distinctive fungus. I have never seen young olive gills on this fungus. Smith described it from a W. B. Cooke collection from Shasta, from a dried specimen; never saw it fresh.

There are a handful of distinctive Pholiota, this being one of them. I don’t need micro to make a firm ID, it’s a distinctive mushroom, a picture is generally good enough. And there is nothing else known like it in the spring in the CA mountains.

Micro is highly variable on a lot of Pholiota. Based on genetic work that has been done on Hesler & Smith Pholiota types, they didn’t realize how variable the micro features are; describing some species two-four times.

Your collection (MO #46530) was included.

young gills should be olive …

according to the original description of “olivaceophylla” by Smith/Hesler. Young gills shown here are not. Got better examples of this distinctive feature that you can put up here on MO, for comparison sake?

no other options for these slimy Sierra/Shasta fruiters?

don’t you need micro details to make a firm ID?

Why "forgotten? It’s right here on page 236 in my copy of Smith and Hesler Pholiotas.

Was DNA run on any of my Sierra Pholiota samples, like from the Yosemite FS?
Else would have had access to those.

DNA run on an actual sample, sure. Micro confirmation of a sample, sure. Photo ID? Maybe not.

but other then that they don’t really look like what we call P. lenta in the east. http://mushroomobserver.org/27532
Not to mention that fact that these grow under or next to snow on wood in the Sierra, the eastern lenta grows on thick duff or small wood debris. http://mushroomobserver.org/46399

Ok, just looked up comment

Ok, I just looked up the comment from Coleman, about material that I sent her in 2008, and she said under the scope they appear to be P. lubrica. So, there is another name for the mix.

Some more obs. of the slimy pale snowbank Pholiota:


And a different Pholiota of the Sierras, more yellow on this one,
as Pholiota spumosa:


Oh, and compare to obs. of P. lenta from Europe to see what people are calling it there…

This is that snowbank Pholiota that we see from time to time. They can get rather large really, and are just barely off-white when young. We have seen this before, but it is inconsistent when it appears or where. I did send material off Coleman also, and she thought it looked like one of the better known Pholiota, but I forget which.

What made you rule out Hebeloma?

not Kuehneromyces…

nor are they malicola or mutabilis.

these were big (up to 7cm across) and “terrestrial” on wood (i.e. growing on the ground but from downed wood). I pictured the cluster, but I also found a single fruit body by itself.

when fresh, the caps were white, but faded with age and a bit of drying to tan.

if this is an undescribed sp., which is possible, then we won’t find a match.
I will check the microscopy against Smith and Hesler’s “Pholiota of North America.”

I also forwarded this sighting to my gal pal Coleman McCleneghan, who studied CA Pholiota for her Master’s Thesis at HSU, for her comments.
