filiform and/or lageniform caulocystidia intermixed with the lecythiform caulocystidia? I think I might see some in the first caulocystidia image, but I can’t see enough to tell for sure.

How big are the caps? Can we see the spores in ammonia? If key two is right then I’m not sure this is going to key out convincingly…

I don’t see any matches in the fan6 key

Would you mind giving it a try?

I’m guessing this will end up in the 2nd Conocybe key…
