Cheilocystidia viewed. I put this collection under the scope within about an hour and a half after collecting it. 600×. Tibiform cystidia or would it be described differently?

I have added a few more cheilocystidia images. My initial reaction is that after a few hours, as the specimens begin to dry, the viewable cheilocystidia greatly reduces. Perhaps I just need more experience.

Of the cheilocystidia would be helpful. Also a reticle for measurement.

Done. I can still examine two more mushrooms for cystidia from this collection if it helps.

Please label your micrographs so we know what we are looking at. When I do microscopy I take pictures of little bits of paper that have the different parts of the mushroom written on it so when I upload them later I know which micrographs are which features. It looks like the second to last is pleurocystidia. What is the last one? Is that capitate cystidia? Capitate cystidia is not mentioned anywhere in the description of P. cyanescens.
