Observation 15397: Psilocybe (Fr.) P. Kumm.
When: 2008-05-24
No herbarium specimen

Notes: This blueing Psilocybe species is found in mulched Pinus radiata in autumn/ winter and seems to be partially secotioid, never really raising it’s pileus above the substrate to disperse spores!
I think this could be an undescribed species closely related to Weraroa novaezelandiae.

Spores much too large!

Here is one of my observations of P. aucklandii with micrographs.

Psilocybe and keys

This does look similar to Psilocybe aucklandii do you have the keys to NZ Psilocybe ?

Speciation,

This could be a form of Psilocybe subaeruginosa that has gone through speciation, I would be very interested in getting the DNA sequencing and spore compatibility tests done so comparisons can be made.
In NZ I have come across two distinctly different forms of P. subaeruginosa, this one is quite different to both in macroscopic and microscopic form.
I have a dehumidifier that dries specimens very well and will make many collections this season coming!
I’m glad you like the images:)

very curious! islands (even big ones like NZ) are great places for speciation….

it would be interesting to see how the genetics of your locally adapted form lines up with those fruiting on some of the larger continents, assuming that this might actually be a variety of an already known species…

better get yourself a dryer, Dude, you are finding some interesting and important collections! And thank you so much for sharing with your neighbors on the other side of the world.

Thanks Curecat,

Psilocybe subaeruginosa is a good proposal, if it is it would be a very distinct form!
Hopefully I can make another collection next season for further examination.

I added Psilocybe subaeruginosa to the list if suspects.

Inski said:
“I did notice the similarities to Psilocybe subaeruginosa when viewing the microscopic features but also noted some differences in the shape of the cheilocystidia, there were some forms of cystidia viewed in these that I could not find in the Ps. subaeruginosa specimens that I viewed, on the other hand as Alan has mentioned the spores do seem to be very similar in size and shape, I guess they could be a distinct substrain or mutation of Ps. subaeruginosa!”
