Observation 59773: Psilocybe allenii Borov., Rockefeller & P.G. Werner
When: 2010-11-26
No herbarium specimen

Notes: Bluing significantly on dried out specimens and when bruised or pinched.

Looked very different than the cyanecens which grow in this same area. Much more convex shaped caps.

These were in hardwood chips among arbor vitae. When picked they pulled up significant amounts of connected wood chips (brick size).

The tendency of many of these things to crack into brown scales as they age make me think they are not in the cyan/fransicians group.

does anyone have a good resource or description for the microscopic characteristics (mikromerkmale) of Psilocybe Cyanescens ?

micrographs

Your new micrographs show mostly basidia, with one cheilocystidia.

Please label your micrographs because it is not always possible to tell what part of the mushroom we are looking by looking at the picture. Label them gill edge, gill face, pileipellis, etc.

To do a complete microscopy workup for Psilocybe you need the cheilocystidia, pleurocystidia, pileipellis and spores. Other genera have other features that are significant such as the caulocystidia. Ideally all micrographs should have a scale so the size of the features can be quantified, but this is only critical on the spore micrographs.

I added 8 pics, not so sure I was successful with the cap margin, but I think I got gill margins okay.

The cheilocystidia pics are helpful, thanks.

The most important thing now is the pleurocystidia.

The best way to photograph that is to take a fresh cap and cut a very small part of the edge off, then make an extremely thin cross section of the cap. The gills will form a sawtooth shape, with pleurocystidia on the edges of the saw blade and cheilocystidia on the tips of the saw blade. This type of section also allows you to see the pileipellis and cap cuticle, which are also important microfeatures.

I’m not sure these help any, but I added some additional pics.

Spore prints on paper and foil
gill edges
gill surface
and standard photos of the mushrooms underside.

1 – It’s an amscope (I believe the model is 490a), I also picked up the m900 video pickup that connects in the third optical port.

The colour is variable based on software settings, I tried to adjust to the “white” of a clear area.

2 – Yes, those depressions were visible through the oculars as well.

As for a scale, I thought the software had that capability, but for the life of me, I couldn’t figure it out. I have a reticle that has measurements, but it wouldn’t be visible through the camera port.

3 – to be honest, I’m not sure of anything I was seeing when looking at the gill edges, I’m thinking I can’t get thin enough sections to get useful images.

scope

What kind of scope did you use for this?

Interesting colors.

The spore pic looks interesting, like there is a depression in each spore. Did they look like that through the eyepiece too?

The first mircograph is rather straightforward, though I usually focus more on the gill edge for those types of shots.

The second one is strange – What are those things? They look kind of like piles of ice. That is not any form of cheilocystidia or pleurocystidia that I am aware of. I think I have seen them in this species too. Where on the gills did you find those structures, and can you get any pics of more of them?
