A year ago I tossed a bunch of shredded leaves, soil, and uncooked veggies, coffee grounds, and lots of other compostable things into a pile in the backyard. I watered and turned through the warm months and the pile went from being 3 feet by 3 feet to now 3 feet by 6 inches. The compost looks good, however, there are some very white balls with long stringy roots in it. Some of them are as big as a marshmallow, while some are the size of a cotton ball, and some are marble size. Attached to each ball are long white stringy roots. I have seen these same stringy white roots under my wood chip mulch and shredded mulch in the gardens after it has been there awhile.

I figured it was a type of fungi, but can't find any info on it anywhere. I am hoping someone here can identify it from the pictures I took.

Other than just being curious as to what it is, I want to know if it is good or bad.

Thanks!
