Well Tetrapyrgos is distinct in having not only tuns of large cystidia all over the fruiting body but they also have VERY cool interesting tetrahedron shaped spores from large knobs! The first time I say them I thought my mind was playing tricks on me! sadly I can’t fins any pictures online… t is truely a sight!

Cystidia are large sterile cells that can occur anywhere on the fungus. They are generally somewhat large and distinctly shaped. This fungus has very large cystidia all over that you can see as the frosting on the cap and stem! and of course we don’t mind :)

just curious

Why was it moved to tetrapyrgos, and what is cystidial frosting? Hope you don’t mind me asking

I can see why it was formerly called Marasmiellus, AND why it was moved to Tetrapyrgos. Is that a cystidial frosting on the stipe? What other charcters (micro, I assume) seperate it out?
