P. liniformans

His suggestion that they are P. liniformans var. americana is ridiculous. I spoke in person with G. Guzman about this taxon a couple months ago. His response was “I don’t really know, if you do, you should publish it.”

In fact I emailed you last night in regards to the microscopy work needing to be done on these specimens. The presence or absence of pleurocystidia and the presence of forking cheilocystidia as paul describes in the taxonomic description of P. Cyanofibrillosa. Paul also told C.A. Harris and I that this was in fact P. Cyanofibrillosa after sharing photos and descriptions of a much earlier find with him while at brightonbush. Specimens were sent to G. Guzman at the universidad de mycologia in mexico, guzman informed us that the specimens we sent him were in fact P. Liniformans.

The mystery continues

I really doubt

That is is P. cyanofibrillosa. I had a discussion about P. cyanofibrillosa with Paul Stamets a couple hours ago. He said that P. cyanofriscosa might be P. cyanfibrillosa because he described cyanofibrillosa based on immature specimens. I told him absolutely not. There is a P. cyanofibrillosa, but it doesn’t occur in California.

To verify, check for pleurocystidia.
