cyanofibrillosa

P. cyanofibrillosa is perfectly documented as far as I know. Since it was described by Guzman and Stamets in 1980 there will be good herbarium collections in a few places.

Cyanofriscosa needs more work to see if it is a new taxon. It matches the description of both P. subaeruginosa and P. cyanescens. A variety rank might be more appropriate than a new species.

to defer to more discerning taxonomic minds than my own. It was a question I raised with him after a talk at Telluride this year, and his answer was pretty unequivocal in the synonymy between the two names. I wish I’d taken more detailed notes. He mentioned something about the type for P. cyanofibrillosa being poorly documented, that certain characters only present in a particular stage of growth were either recorded or unrecorded as being diagnostic for the species. In the extremely unlikely chance I can reach him for comment, I’ll post back here.

As far as I know, the only evidence for this undescribed species being the same thing as P. cyanofibrillosa is Paul Stamets anecdotal assertions that it is.

Danny, Paul is not an authority on this species and its identity. In the past he has agreed that this species is not P. cyanofibrillosa after pointing out that the microscopic features (that Inski states below) don’t match, and him being unable to provide any evidence for this species being P. cyanofibrillosa.

If this is the case the description for the type collection of Psilocybe cyanofibrillosa is not a good representation of the taxon, it mentions cheilocystidia which are fusiform to lanceolate, the line drawings depict cells that are often with a bifurcate neck, it also mentions that pleurocystidia are absent. The micrographs that Alan has provided at this site made from collections of P. “cyanofriscosa” show lageniform cheilocystidia, the bifurcate neck looks to be either very rare or completely absent and pleurocystidia that are quite common. I believe the fungus they are calling P. “cyanofriscosa” to be very closely related to the southern hemisphere species P. subaeruginosa if not conspecific. I see Alan has provided a DNA sequence for some of the collections of P. “cyanofriscosa”, maybe someone would like to compare this with a sequence from P. cyanofibrillosa if there is one available.

On the authority of personal correspondence with Paul Stamets.

it’s not a published name or even correct Latin.
