Recognized by sight: The species concept of Agaricus (Panaeolus) cinctulus is based on a drawing made by Bolton in 1791. No type collection exists. Since it is not possible to know whether Bolton’s species was Panaeolus subbalteatus, P. olivaceus or P. fimicola, I consider Panaeolus cinctulus to be a nomen dubium.
Based on microscopic features: The gill faces need to be checked for sulphidia; the presence of these would indicate that it is probably Panaeolus fimicola.

sorry, late night and all. i plan on doing the updated stuff when i do micro like i do most of the time. Take a look at my Olivaceus observations, definately have zonate rings, but are way less thick, and do not typically show brown in the pileus, if they do, its when its dry, which cincts look very different dry from them also. but yes i can tell your just poking fun, and thats great! keeps me on my toes, somebody should HAHA.

1000ft, directly on horse poo. perfect black spores. i love micro though. so it shall de done!

It is…

…hard to tell what they are growing from in your photos and you didn’t include that information in your notes. That with the blast is pretty good evidence, you have upgraded my confidence. Also, I’m not sure the other possible species are so zonate when still pins. I still do want to see microscopy though. ;)

Seriously though, I meant that as tongue in cheek. :) And yes, I have seen P. olivaceus with similar colors, idk enough about P. fimicola to say one way or the other for it…

Fimicola and olivaceus with a light pileus? Olivaceus and fimicola growing directly off Horse dung?

probably the same mycelium, about a few meters away…

You know byrain if there was any chance that this could be something else i would micro, and you know me, there will be micro for these two observations anyways. The one i linked has the BLAST for goodness sakes. Im in the middle of moving Byrain.. Give me a few days lol. You are just selfish and want some sexy micro pics ;)

I found a….

…lbm, I know there are more than one species that looks like it, but screw all that hard work, imma just call it the most well known one! ;)
In this case you could likely be right, but still, would be nice to see the neccesary documentation, for example P, olivaceus and probably P. fimicola too can have zonations that look a lot like P. cinctulus when the hygrophanous caps begin to dry.
