Panaeolus from horse pasture

Today I went into the horse field and found a few mushrooms: all on dung which I assume to be Panaeolus. Are these interesting to anyone?

The first is this one(1).
 
I was unsure whether it was immature, but I picked it anyways as I was unlikely to find it again. I also picked two tiny pins. A few hundred feet away I found another "closed up one"(2), however the second one seems to be darker. 2 was in an area with more shade, otherwise a similar habitat. I chose to keep these specimens intact.
2 & 1


The second one shared its patch of horse droppings with the following Panaeolus mushrooms:
3. This was small and fragile, Light capped and stemmed. stem darkenend a bit with unintentional abuse


4. small and light capped and fragile, reddish stem.



5. A cinctulus or a pappililaceus that is perhaps too far gone to ID

Panaeolus antillarum (3, 4) number one could be panaeolopsis sp. (edit) or young Pan A.

I think you might have mostly Panaeolus papilionaceus and a few cinctulus maybe. I would think that antillarum would be larger. I'm not authority on the matter.

I could see 1 & 2 being young paps, pre tearing perhaps
3 was very light stemmed.
3 and 4 were much smaller and much more fragile in the cap than the Pan paps I found in the spring.
3 & 4 did not have obvious ruffling like the paps in the spring
Is pappilionaceus a broad complex of phenotypes or is it likely to be phenotypically stable?
I'll read up on antillarum.......

All your pics show Panaeolius papilionaceus sensu lato. Maybe wintersbefore has some insight as to whether Panaeolus papilionaceus is a species group, or just one very widespread species.

I tend to believe there are slight differences in the morphology based on a range of factors. I'm not totally convinced either that Panaeolus campanulatus, Panaeolus sphinctrinus and Panaeolus papilionaceus are all the same species and that there may be slight differences between them, similar to the "Copelandia" grouping for example.
I have an unreasonable amount of photos of Panaeolus papilionaceus, some similar to yours. If you'd like I can upload them to my gallery so you can have a look.

Yea there might turn out to be a valid species or two in that group. How much good it does to separate them out from Panaeolus papillionaceus is a philosophical issue.
