As warriorsoul mentioned, it would be interesting to compare these with P. baeocystis and also P. aztecorum var bonetii, your collection could actually be the latter mentioned variety if it was found at 3000 meters above sea level!

P. aztecorum looks more like cyanofriscana than baeocystis......odd.

Cactu,
?Que chingonas fotos(fucking awesome pics)!


I felt an uncontolable desire to get out of the car at that spot and just after the light faded, I busted out the cell fone light, and said a few words to the mushrooms, cactu style, and BINGO!
I learned more from that guy in 3 days than I have in 20 years of hunting mushrooms!  Thanks hermano, I'll see you soon.

Hasta,
Blondie

hope to  see you soon to ..

Very interesting find Cactu! Did you notice the caps to be strongly hygrophanous? The description also mentions them easily bluing..Got a pic of a dried specimen?

Any preliminary microscopy done?

---

very strongly hygrophanus for sure , they blues  but the  blue fade as inski mentioned and  is not as the blue iam use to see  dried speciemn i can take a few  for ya . let me put how they change .




so  that night rain fall and they all got pretty wet but in the morning the sun hit good and at that altitute the wind is  very cold . i love that mountain ..
this is how they look when they are young and  humid


look the variation of a pin and a old specimen i dont know how much they last , but i guees like 5 days , when they are old and  humid they remind me of stunzii .

growind next to a log  of a plant of hight altitude

there where  twing and  branches and  log  for then to eat,

en la mañana todo se ve mas claro

this coprinus also grow there





si si  las mejores fotos de aztecorum en el internet solo aqui



the sum is rising more and more  the dew is going to evaporate soon

after el gwero pick all this you can notice how they are drying


they dry fast

the pile of gwero and my pile in my hat

notice how white they are now ¡¡

Workman i got my info here..
Variation, Distribution, Ethnomycological Data and Relationships of Psilocybe aztecorum, a Mexican Hallucinogenic Mushroom
Gastón Guzmán
Mycologia, Vol. 70, No. 2. (Mar. - Apr., 1978), pp. 385-396.

"Psilocybe baeocystis as I studied in the type (Sipe 754, Nov. 1,
1945 ; MICH) and in many collections made in the Pacific Northwest,
is very hygrophanous and, in some stages, quite similar in appearance
to P. aztecorum. The only difference found in the Mexican fungus
is in the shape of the spores in face view. In fact, the mango form of the spores of P. baeocystis is a good character which can be used to separate it from P. aztecorum.

It is probable that P. aztecorum originated from a subtropical
species such as P. mexicana Heim which has the biggest spores of all
species in the subtropics, (7.7-)8.8-9.9(-12) x (5.5-)6.6-7.7(-8.2) x
6-7 pm (from the study of the type in PC) and mycenoid fruit bodies,
but without a white pileus, some subrhombic spores, and terricolous
to sublignicolous habitat. Psilocybe mexicana, on the other hand,
seems to have had its origin from tropical terricolous species such as those recently described by the author from evergreen tropical forests, which have small spores and brown cystidia. Thus, it seems that species of Psilocybe have small spores and brown cystidia in the
tropics, moderately sized spores and hyaline cystidia in the subtropics and large spores and hyaline cystidia in the temperate or cold regions. This same phylogenetic sequence is observed in the size and complexity of the spores of Scleroderwza (Guzmin, 1970), which show small and simple spores in the tropics, as in S. sinnamariense Mont., and large and complex spores in temperate forests, as in S. hypogacuwz. Thus Psilocybe aztecorum is, in Mexico, one of the most highly evolved species of the genus, and it seems that P. baeocystis and P.quebecensis had their origin from this Mexican species, through two different phylogenetic ways, through the high mountains, Psilocybe cyanescens probably had its origin from some stirp of the subtropical species, close to P. mexicana. From this point of view, P. aztecorum var. bonetii is more primitive because of its smaller spores and presence at lower elevations."

The similarity to baeocystis is interesting.
Are all the basidia 4 spored like baeocystis or quebecensis?
or are they 1,2,3,and 4 spored like Psilcybe aztecorum?

Maybe this is a third distinct species descended from Psilocybe aztecorum that evolved parallel and seperate to quebecensis
with this scenerio the maine species could have an explainable resemblance to Psilocybe baeocystis from its initial split with
Psilocybe aztecorum var. aztecorum.

Bump!

Chasing old threads like this is a really exciting thing.

So many beautiful pictures! Has it been considered
making a pictorial book?

Mainly for the sheer enjoyment, but also useful in
showing variations in different species.

I know I'd buy one...
