04 September 2010 - We went to a Tomato Festival at West Dean. Arriving early, we were one of the first few cars in the parking field and we found some fantastic horse mushrooms.

What Are Horse Mushrooms?
Agaricus arvensis - related to, and resembling the common white mushrooms sold in every shop, but these are a bit different - they're more robust in stature and size - growing to the size of a dinner plate in some cases (as indeed in this specimen).
They also have a more intensely mushroomy flavour than the typical commercial mushroom - especialy when mature, when the gills turn deep chocolate brown and the whole mushroom develops a flavour that is almost meaty in its depth and complexity.
IT IS YOUR OWN RESPONSIBILITY to take adequate steps in identifying any fungi you gather for the table - doubly so if you are intending to share them with someone else.
Informal descriptions, such as the one on this page, are not adequate for full identification - it's just good sense to independently verify everything you read here.
Rules of thumb or folk wisdom identification methods are frequently unreliable.
Consult a comprehensive identification guide (I recommend RogersMushrooms.com and Wild Mushrooms Online) or best of all, talk to a living human expert mycologist.
This one was fully 9 inches in diameter.
After picking I trimmed off the bottom of the stalk, which was covered with sandy soil - with a big mushroom like this one, the only way to transport it is flat, upside down.
(If you put it flat, right-side-up, it will drop dark brown spores on everything).
I picked a good number of smaller specimens too.
Sadly, but not unusually, about half of the mushrooms I picked were inhabited by maggots and had to be thrown away.
(I suppose I could have just looked a little less closely and chosen not to care, but I didn't fancy that).
Still, there was a good pan-full of mushrooms.
I fried them gently in a little vegetable oil, then when they were about halfway done, I added a good lump of butter to finish them off.
I served them on slices of toast - horse mushrooms are uniquely suited to this presentation, as during cooking, they release a rich, dark, gravy-like juice which is too good to waste - and a slice of toast mops it up perfectly.
Oh my! They were very, very good indeed.
