Can anyone identify this "cat food fungus" ?

Normally we try to recycle our organic material through the compost bin in the backyard, but in the winter with two feet of snow on the ground that becomes impractical at times. Last winter when we had surplus soft canned cat food, we stored it in a plastic bowl in the garage.

It stayed frozen through the winter, but as spring approached the old cat food surprised us by sprouting a magnificant crop of some kind of fungus. [Or it could be a slime mold - I have no idea]. It looked like black hair, and up close there appeared to be some type of fruiting bodies on the stalks.

I searched the 'net, but came up short. I wonder whether there's a TYWKIWDBI visitor with experience in mycology who can offer an educated guess as to the identity of this interesting growth.

Update: Thanks! and a tip of the hat to "Kentyman," who, within a couple hours of my posting this, identified it as Phycomyces nitens. Many pix at the link, growing on bread and cat dung! It has also been reported growing under bird feeders filled with Nyger seed, presumably growing on bird droppings rather than the fallen seeds. We have thistle feeders at the house too, so I'm sure the I.D. is correct.
