Idk if I would succeed either, out of the two Pholiotina collections I have scoped I could only find cystidia on one. I also I really don’t think I could get around to trying for a while…
My suggestion is to try another specimen, assuming you haven’t already, maybe one of those pins would be a good one to try.
Debbie: Thank you!
Byrain: My two gill edge preparations were made exactly as you’re describing—a very thin slice along gill edge (under dissecting scope), then looking at it first without any mounting medium, then mounted in Congo Red followed by KOH. I’m sure I was looking at the gill edge and there were no obvious cheilocystidia on it. My first microshot is of a gill edge.
I tried again this evening and again there were no ch’s. If you want, I can send you the dried collection.
Yea, I have also had difficulty in finding cystidia on Pholiotina, it might help if you get a very small bit of only the gill edge, maybe even using a dissecting microscope and then smash it. Unfortunately I think you need cheilocystidia for an id, collections keying to P. teneroides, P. vexans, and P. utricystidiata have also been found in CA. See observation 7291, observation 127696, observation 65857, and observation 130970.
Edit: I don’t think I fully woken up yet…I recalled cheilocystidia differences in the key being further up, my mistake.
Edit 2: The spore size still fits P. utricystidiata too, but what I have called that in CA was a small species growing with a potted plant, cheilocystidia should distinguish the two species.
once again, you have amazed me with your collections and photography.
Spores 9-10 × 5-5.5. Basidia 4-spored, one measured 30 × 8. Interestingly, there were no cheilocystidia to be seen; and I made two mounts with samples from two frbs. The gill edge was fertile in both cases.
Using FAN6, it comes out as Ph. rugosa_. The other two possibilities (_arrhenia and hadrocystis) have smaller spores.
Byrain, have you experienced this difficulty with finding cheilocystidia?
running this through fan6?
