|The largest of the group, under 3 inches across. Before the snow fell and froze solid, slugs had been feasting on the fur.|
|A few of the babies. These are all under half an inch wide, and as white as the snow beneath.|
These are probably Trametes hirsuta. ("Hirsuta" means "hairy". Good name. They are hairy, although the hair is arranged in stiff peaks, as if someone used too much hair gel.)
These mushrooms grow mostly on dead hardwood, and slowly return it to the soil to nourish the next generation.
Somehow, I'm never tempted to taste a bracket mushroom, or wonder about its edibility (although some are edible, I know), but mushroom guides routinely mention this. On the E-Flora page about T. hirsuta, under the "Edibility" heading, a contributor has commented, "Too tough." Looks about right. Too hairy, besides.
