I would like to see the tissue under the microscope to see the disorder at that level. If you ever get a chance to dry material that represents that state of affairs, I would really like to see freshly dried material…that is to say material that has not developed any mold.

Mold is such a plague with dried material of pruittii.

Very best,

this specimen was found in the same general area as Tao’s recent observation 186805.
My experience with this species is that the distinct warted appearance gets really disoriented and/or obscured quite easily depending on the environmental conditions.

I have had the pleasure of watching a small patch near my house produce 10+ fruitbodies over the course of a couple weeks (unfortunately the slugs get to them rather quickly since it in an urban area). The young caps are all distinctly warted, but the older ones are often quite matted-tomentose (any radial pattern would be more difficult to detect) in age.

Hello, Christian. The form of the volva visible on the cap surface at highest magnification…

is a new one on me. Top bad you don’t have a specimen. My impression has been that there is usually a stromg radial distribution of the hyphae and in the volva. That is not present in this specimen.

Very best,
