The blue staining species are in a sister clade to Galerina and have been placed in the Hymenogasteraceae, if the rules of nomenclature were followed the new generic epithet for the blue staining species would have been Weraroa, I’m glad Jan retained the name Weraroa as the specific epithet when he proposed the new name P. weraroa, this had to be done because the binomial P. novae-zelandiae was preoccupied.

Actually, a few people are jumping the gun! There are two distinct clades within the genus Psilocybe- a bluing and non-bluing clade. Because the genus is polyphyletic and because a member of the non-bluing clade is the type species (P. montana), the non-bluing clade should be retained within Psilocybe; but then you need a genus name for the bluing group, and since Weraroa is a polyphyletic dumping ground for secotioid species, and the lectotype is W. novae-zelandiae (phylogenetically shown to be within the bluing Psilocybe clade), the next available generic epithet is Weraroa.
But some mycologists decided that popularity is more important, and took steps to conserve the name Psilocybe for the bluing clade (Prop. 1757) by changing the type species to P. semilanceata, and thus, the non-bluing clade returns to Deconica.

Personally, I think the motivation is terribly skewed, but I am in the minority it seems. In any case, I hope that clears up any confusion!

All of the species in the Genus Psilocybe that do not contain the hallucinogenic compounds Psilocin and Psilocybin are in the process of being transferred to the genus Deconica, many have already been reassigned but there are still many that remain in the genus Psilocybe, it is just a matter of time before someone works on the rest, P. novae-zelandiae is one of those species that should be reassigned!

I find it strange that several people prefer Deconica as the genus name both New Zealand herbarium and Species Fungorum (Dictionary of the Fungi, 10th ed) have Deconica as a synonym of Psilocybe.

Am I missing something or are a few MO people living in the past?

Good call!! Very cool Psathyrella! If you can collect and dry it Inski, that would be cool!

I have my doubt as to this been Psilocybe novae-zelandiae has far to many scale on the cap and stipe. I would be looking at Psathyrella asperospora. Have a look at its spores they are very distinctive.

Is this P. novae-zelandiae in the bluing clade as well??

I didn’t realize that there was a P. novae-zelandiae as well as Weraroa novaezelandiae!

Excellent documentation and photography- as usual!
