San Francisco I.D. Request

I stumbled upon these yesterday in Daly City. They look like Psilocybe Allenii to me but I'm new to hunting and I was hoping to get a second opinion. Thanks in advance!

This species seems so common. How wasnt it discovered until recently?

The microscopic features are the same as Psilocybe cyanescens - it was sent to Gaston Guzman multiple times, but each time he scoped it he replied that it was just a convex P. cyanescens. The difference is obvious to anyone who finds them, but to people who just receive them in the mail, it's a whole lot like P. cyanescens. And also P. subaeruginosa and P. azurescens, and it's also super close to P. weraora.
The whole Psilocybe cyanescens complex differs by only 5 base pairs in the ITS region, and some of the species are really close - P. azurescens is only 1 ITS base pair from P. subaeruginosa from Australia - but the chemical and morphological features are a little different.
1 base pair would normally not be significant in ITS, but it's a repeated pattern over many sequenced collections, so it does seem to be the case that you can tell P. azurescens from P. subaeruginosa by looking at one base in the ITS.

Yup P. Allenii. I was wondering that same thing, interesting stuff Alan

Thanks for the enlightenment Alan. Side note: Hope this doesn't sound creepy but I had an awesome time following you around Sutro Park Christmas Eve. Learned a ton.
