What do you guys think of this idea.

What if I mulched my vege garden with chopped straw or finely shredded wood chips which were innoculated with some sort of edible mushroom. I figure I'd get a nice mushroom harvest every time it rained, and also it would help break down this matter quicker for the veges.

It seems like a good idea to me. If it could work, does anybody know of a good mushroom varity for something like this?
