 Hpoo as a substrate for gourmet edibles?

I spent a lot of time with the search engine trying to find posts about using horse manure (hpoo) as a substrate for growing gourmet and edible mushrooms. There's not a whole lot of mention on this forum of its use in that respect. I now have access to the output of two horses and I'm looking for a way to transform it into mushrooms. Does anybody out there have any experience or opinions on this?
What mushroom species would hpoo best for? Oysters will eat anything, it seems, and there are a couple of posts referencing growing king oysters on a hpoo substrate. (But is it worth the extra trouble vs. straw or sawdust?) Agaricus is an obvious choice, though the traditional composting seems like an awful lot of work and I am not a big fan of Agaricus. Perhaps King Stropharia? Any other species?
What is the best way to use horse manure?
Most recipes on this site (for P. cubensis) call for mixing the properly aged and moistened hpoo with vermiculite. I am not going to be spending big bucks on bags of vermiculite, so that option is out.
Does hpoo perform better pasteurized or sterilized?
What are the benefits of using hpoo?
What sort of supplements should be added to horse manure? Gypsum? Lime?
Can hpoo be used as a supplement for other substrates such as straw or sawdust? At what ratios?
Is it worth even bothering with the hassles of horse manure when I have access to other substrates such as sawdust and straw? Would hpoo best be used just by throwing it in the garden compost pile and feeding the plants?
Yes, this is a lot of questions, but I thought it might be nice to get all of the information about horse manure for edibles in one place. I have collected a few lbs. of nicely weathered dung and will be beginning my own tests and trials in the upcoming weeks.

1.) Pasteurized
2.) "I now have access to the output of two horses" In your case, access to free substrate.
3.) Gypsum, Lime depending on the species. IIRC Agaricus don't like Lime? Could be wrong about that...
4.) Yes. Because of the consistency of manure many growers use straw. The fibers act like a mycellium highway to penetrate into more dense supstrates. As far as ratios that's up to you. You could use anywhere from 90% manure/10% straw or 90% straw/10% manure
5.) Not really. Not unless your doing something like Agaricus. I don't like manure. It smells.
All that being said, since you also have access to sawdust you could make some sawdust spawn, mix it into the stables and see what happens.
Good luck, and good growing.

I just reread your last question and noticed it had two parts. Yes, that will make a great fertilizer for your garden. Throw some sawdust spawn in the mix and you'll have a kick ass garden.

I second fungus_tao's suggestion: use sawdust and make spawn from that, then throw it into manure (perhaps mixed with some straw). I wouldn't recommend using manure on its own as spawn, unless you have nothing else to work with.
--------------------
I am looking for the following edible cultures:
- Chicken of the woods (Laetiporus sulphureus)
- Wood blewit (Lepista nuda)
- Cauliflower (Sparassis crispa)
My trade list of available cultures is in my Journal.
