Without sounding like an esoteric voice, I’d rather not name drop, but it was done in Europe by a professional who studies fungi with particular interest in the genus Psilocybe. All of the cystidia have been, with certainty, called cheilocystidia – and I am moving forward to obtain clarification.

Lacks pleurocystidia after closer examination

My observations were not pleurocystidia as previously written. Species matches Ps. pelliculosa after independent microscopy was performed.

Spore thickness

You can find spores laying on edge and measure the third dimension. Often the spores on the top of the cap and on the stem are laying random directions.

I didn’t know I could measure thickness. I’m guessing I’m going to need both a method and better equipment?

Those spores look thin and almost collapsed. How thick are they?

Well I did 15 gill cross sections of this collection. None of them were suitable for the long/short/long/short gill film I inspired myself to procure. Another day, a new collection – hopefully! Peace…

Spore prints

Spore prints can vary in color between collections.
The ones found yesterday that were printed all printed lightly and vaguely brown.
Today I was able to see more purple hues in the printing process, but I still would not recommend an eye-ball over a Magnifier Task Lamp.

Video! And…
