If you couldn’t find pleurocystidia, I highly doubt that anybody could. I consider your microscopy mycological canon.

Do you think these are the same species? I wonder if the lack of pleuro in this obs highlights the incredible variability of cystidia In this genus, or if it indicates that these are different species.

They look borderline indistinguishable to me, with the exception that the specimens in this observation seem to be much drier than the others.

A higher mag look at the pileus trama may be in order…

And the others have it.

But if you send me your address I will send you some that you can check.

This seems extremely similar to the two recent observations from the same location. Even the spores seem to be the same size and shape, unless I’m missing something.

Did you look for pleurocystidia in this one? Was the pileus trama radial?

great…
