The second mushroom was frequently seen in the grass next to the dung and looked very similar in shape, but the cap and stem were dark and the caps were slightly larger. My first identification is for Panaeolus rickenii (wrong, see below). I could not get a closer look at the mushrooms because of the barbed wire and electric fence. A third mushroom was also seen in the dung. I think this latter one was a species of Conocybe. The fourth species has a flattened cap and was much larger, estimated at over 60 mm cap diameter with a stem that could not be seen.
Panaeolus papilionaceus var papilionaceus. You were close! P. rickenii (now called P. acuminatus) is more purple brown.

Mushrooms discovered in the afternoon were a dozen the white-capped species growing on horse droppings piled up on the edge of the field by the Steyning Road, Old Shoreham. The white stems of this species were hollow. This was the Snowy Ink Cap, Coprinus niveus.
They looked like Panaeolus sphinctrinus to my inexperienced eye.

On the edge of the horse's field on the south-west approaches of Mill Hill, (south of the A27 main road), on the pile of dung next to the footpath two clumps of about 20 mushrooms were growing. It is a species of Conocybe. There are seventy nine species of Conocybe found in Britain.
