Your specimen is not a Panaeolus and appears to be a Psilocybe, specifically Psilocybe semilanceata. This is also likely the same species as the suspected P. strictipes which were growing nearby despited the seemingly different appearance.
Psilocybe semilanceata is very variable in appearance and doesn't always have the classical liberty cap shape and occasionally are nearly plane. The stems of your collection are classic semilanceata and are very non-panaeolus like. The microscopy of the spores is also consistant in color, shape and size for Psilocybe semilanceata. The time of year (November) and the grassy habitat near a horse stable are also in agreement. I've personally found many liberty caps near a horse stable in a grassy drainage ditch.
By the way Cleanjar, you can actually see dozens of variations in the shapes of the caps in the assorted images I have posted below for you to look at and remember that all Psilocybe species have many of the same ones in these lib caps in other species of Psilocybe. Just like the Cubes can be cultivated and sometimes get very wavy big magnificent caps like P. cyanescens does.
Yes they all are P. semilanceata and I too have collected them in horse and cattle pasturelands at the Bartels Meat Packing Plant Across from the Fern Ridge Reservoir on West 11th outside of Eugene heading towards Elmira/Veneta, Oregon. Right at the fern River Reservoir street crossing the first field across from Bartels has a nice herd of horses, about20-30 or so. The libs are known to spread along the roadways and on the sides of the railroad tracks on Bartels property right up to the mud pits when the water levels are down and people wear the waist high boots and collect arrowheads on the right side of the swampy reservoir, and if you cross the highway on 11th and over the railroad tracks into wooded are you come out in some pastures and north of those are the fences which separate the rest of the swamp areas from the Plant.
Use to pick the same in Marymore Park in Redmond and in the lawns in the Seattle Arboretum at woodland Park lawn.
And Clean jar, there are dozens of variations in the shapes of the caps of P. semilanceata. They can even be completely conical as a Conocybe, but have a different shape, a nipple and a protrude as does one of yours in this image.

Yes, as Workman said they are variable. However, I posted tan image with two libs with bell/conical Panaeolus shaped caps to show how that is common in certain collections and yours all are P. semilanceata and I too have collected them in horse and cattle pasturelands at the Bartels Meat Packing Plant across from the Fern Ridge Reservoir on West 11th outside of Eugene heading towards Elmira. Veneta, Oregon. Right at the fern River Reservoir street crossing the first field across from Bartels has a nice herd of horses, about 30-40 or so. The libs are known to spread along the roadways and can also be picked on both sides of a road way, country road which has pastures on both sides of the highway, and on the sides of the railroad tracks on Bartels property right up to the mud pits hen the water levels are down and people wear the waist high boots and collect arrowheads on the right side of the swampy reservoir, and if you cross the highway on 11th and over the railroad tracks into wooded are you come out in some pastures and north of those are the fences which separate the rest of the swamp areas from the Plant.

Well it seems that you have some kind of security on your images as they will not copy to my desk top. I wanted to point out the features I was going to discuss but your images won’t copy.
However, some pf yours or most have an acute incurved margin at the base of the cap to the stem. You cannot see any striate margin that is a characteristic common with fresh moist lib caps where you can see the lines of the gill plates showing through to the outside of the caps as they change color (hygrophanous reaction) in your image. And many of those in the images I am posting have permanent incurved margins that will never open any further and others open up like an upturned lampshade. Some have a distinct pin cap shaped nipple, others have a small round flat cap; some have protrudes and nipples while others have long skirts of their stems and then you see some with no nipples and cone shaped. The brownish-tan ones have a striate margin and you can see the lines on the caps, and then many in a few photos have become hygrophanous, meaning they are changing color as they dry in the hot sun or even from a cold front. The stems are pithy and will curve around your fingers.
Here are some examples of various shapes of P. semilanceata, and while many stems tend to grow to 4-6 inches at times, in fields where sheep graze, the caps never get taller then the grassy area they are growing in. This is similar in patches of blue ringers (P. stuntzii, P fimetaria and P. sierrae).
And P. strictipes tends to have more of a cone-shaped and even conic shaped cap.
And usually in fields of libs, they can allso have many which are sterile and have white gills with no spores.
I had to retype all of this because my time at Mycotopia expired and when it does I have to re log-in and I have to turn off the explorer and re log n to get this posted so I did it on word and now will post my response with no notes to the images as my eyes are burning. Was up most of the night still coming down off of the steroids the doc gave me to open up my lungs, mjshroomer.

Liberty caps were the first magic mushrooms I picked. I found 24 medium ones the first day. ate them that night and felt i should have eaten may two times instead of what I atel
So I picked over 400 the 2nd day. That night I told my wife maybe forty wuold be a good dose for use each. She said no lets do sixty. So I said cool, but when she wasn't looking I put about ten of mine back.
Wehad a Wasson/Hofmann ceremonial Mazatec venture and voyage into another demension. They are my favorate but I have not eaten any since Vancouver BC of 2003.
OF course P. samuiensis and P. antioquensis are close to P. semilanceata, Sams grow in both Angkor Wat and P. antioquesnis as well and Sams grow all over Thailand now. A new collection and lab work form Ranong Province facing India on the Andaman Sea area is alsop crawing with them.
I want you to also note Cleanjar that some libeety cap caps have a flat round pencil sized cap which is flaat and some have a bump kind of cap on them., then long caps spreading outwards and more long and thin with bulges like the caps have a pregnant look to them.
I want to post a few more below because of their unusual shape diferences.
One kinda looks like a breast with a nipple waiting for some flying or crawling insect to come suck on it:
The Breast of liberty cap, yum yum:
