Mycena "sp-AZ03" that Scott Ostuni spotted near Fox Mountain, Colorado last year. I just got a sequence of it back from Mycota Lab. This probably undescribed species currently only known from Colorado and Arizona.

Mycena sp. 'amicta-HRL01' - A species in the Mycena amicta group with only two observations on iNaturalist, both in the east bay area, California, USA. This species has blue colors on the lower stem, an amazing stem texture due to abundant caulocystidia and a separable gelatinous pellicle.
Collected November 23, 2020 on the UC Berkeley campus and sequenced recently by @mycota.lab.

The Shulgin lab, located in the Bay Area, California is where over 200 psychedelic drugs were invented. I am going to be teaching DNA barcoding and giving a talk on new discoveries in the taxonomy of psychoactive mushrooms at the Shulgin lab on February 22. Tess Burzynski and Mandie Quark will also be giving mycology related talks.

Ps. aztecorum from the volcanic forest of Nevado de Toluca, Mexico.
This beautiful species was first described in 1958 by mycologists Gastón Guzmán and Roger Heim. The species name aztecorum translates to "of the Aztecs," paying homage to the ancient Aztec people, who are believed to have used this species ceremonially.
Ps. aztecorum primarily occurs in high-elevation coniferous forests of central Mexico, where it grows on woody debris often among pines, firs and Senecio cinerarioides. In Mexico it occurs at altitudes between 9,500 and 12,500 feet, occurring in cooler, alpine environments. Recently this species has been found (and verified by DNA barcoding) in California, Oregon, Colorado, Arizona and Southeastern Canada.
This species is closely related to Ps. serbica and Ps. caeruleorhiza, two other macroscopically similar woodlovers. The literature says that it is closely related to Ps. baeocystis and Ps. quebecensis - however Ps. baeocystis is a distant relative which is closer to Ps. semilanceata and Ps. quebecensis is a synonym of Ps. aztecorum.
Photographed during my September 2021 central Mexico expedition. https://m.primal.net/NxCR.jpg

Hello Nostr, I'm Alan Rockefeller, a mycologist with over two decades of experience studying wild mushrooms. I enjoy teaching DNA barcoding, field photography, and microscopy.
I spend half my time in the lab and the other half in the woods, especially the western USA, México and South America.
I post all my photos and DNA barcodes on iNaturalist and Mushroom Observer a lot,
Follow me for mushroom photography, mushroom events and insights gained through DNA barcoding.
