"Psilocybe while the non-bluing clade were transferred to the genus Deconica." http://en.wikipedia.org/wiki/Psilocybe
From this thread:

Alan Rockefeller said:
It wasn't moved into Deconica because it contains no psilocybin or psilocin, it was renamed because it wasn't closely related to the type species of Psilocybe. A side effect of moving the non-active Psilocybes into Deconica is that all of the Psilocybes are active.
There is no rule that Psilocybes need to have psilocybin, it is possible one could be discovered which lacks it. But all known species of Psilocybe do contain psychoactive tryptamines.
I was in error. I misremembered the quote. My bad

Psilocybe atrobrunnea is a nomen dubium, the type collection was lost and the description could apply to multiple taxa.
Psilocybe fuscofulva is a better name for this taxon. It is closely related to Psilocybe semilanceata, P. silvatica and P. graveolens, however does not stain blue or contain any psilocybin or psilocin. Even when grown on media enriched with triptamines, gc/ms analysis still shows that it is completely psilocybin free. This is the first known Psilocybe that does not have any psilocybin. The paper on all this was written by Jan Borivicka and has been submitted for publication.

Now I know! So it must have lost the trait secondarily.

That's really neat, actually.
