Observation 6156: Pholiota velaglutinosa group
When: 2008-01-19
Herbarium specimen reported

Notes: I have been calling this velaglutinosa, but now I am not so sure. Finally found young material, and the partial veil is heavily fibrillose not glutinous, and forms a distinctive sheath on the stipe(similar to a cystoderma).

Any ideas? It is fruiting everywhere right now, from the East Bay to the Sonoma Coast…

I have collected plenty of P. velaglutinosa which had an obvious glutinous PV (if you wonder what this looks like, think unbroken Gomphidius slime veils).

AS I mentioned for THIS sighting, young specimens had distinctively fibrillose PVs. They were NOT on wood chips, but in pine duff.

Despite its similarities, this is not velaglutinosus.

Pholiota rubronigra

I sent my photo to ace pholiota gal Coleman McClenaghan. Here’s what she came up with.
Yes, I know that the glutinous veil can disappear. that’s why I at first called it velaglutinosa. But, finding the young material told me different. Here’s Coleman’s feedback. I am going say that it is rubronigra, or something close to it…" The photo looks closer to P. rubronigra which has a viscid cap, HEAVY FIBRILLOSE VEIL (my emphasis. D.) that can leave a ring, and grows on pine (Did I imagine pine needles in that photo?). It is
in the same Stirps as P. velaglutinosa." C McC

I’d call it P. velaglutinosa

Several species fit into this group. Not only would you need the microdetails, but the colors of the cap (reds, browns and yellows) when fresh, the color of the context of the stipe and the degree of slime on the cap. Others to consider are: P. ferrugineo-lutescens if it bruises yellowish, P. ferruginea, P. hypholomoides, P. lubrica var. luteifolia and P. rufodisca.

In my experience the cap slime and glutinous veil on Pholiota velaglutinosa dry out fairly rapidly, often leaving fairly thin fibrous looking remnants on the stem as shown on the photos. I just posted(# 6171) a couple of photos showing P. velaglutinosa in all it’s fresh slimy glory.

Debbie, I wouldn’t get too hung up on the macroscopic details in this instance… Though I admit, I cannot imagine what a “glutinous veil” must look like. I am quite certain they are P. velaglutinosa, having identified them for myself about 3 weeks ago. Peter and I had found these mushrooms while hunting, and we were both uncertain. We each took some home to ID, and Peter later agreed with my ID. They were definitely the same species that you have here. Darvin and Douglas also agree… So perhaps the difference in veil characteristics is due to something environmental, or perhaps just phenotypic variation.
You’ll have to describe the veil to me in more detail this evening…

Second P. velaglutinosa

I’ll second the P. velaglutinosa, but just going on what Darvin told me once. If you take a look at observation 2598, you can see the same fibrous veil there. But I’m not sure where the best source on this Pholiota, and other similar Pholiotas might be found. That observation was only going on Darvin’s say so, so that’s all I know. Darvin should comment more perhaps, if he has better Pholiota sources.

Any other feedback on this one?

What is bugging me, Erin, is that it didn’t have a glutinous partial veil, which I have observed on other specimens of velaglutinosa.

The one young specimen that I found at SP last weekend had a heavily fibrillose partial veil. How does this jibe with a velaglutinosa species description?

That is definitely P. velaglutinosa. The partial veil in your photos is consistent with that species. Also, try peeling the pellicle next time you find some viscid specimens. It is extremely sticky and especially thick and stretchy.
Indeed, they are everywhere in Northern CA right now, especially preferring woodchips.
