Shaggy Scalycap?

Throughout the autumn we have passed this patch of fungus at the base of a roadside tree. My smartphone captured stages of its life. Click twice for more detail.

Identification of fungi is not easy. The scales on the cap suggest this is a shaggy scalycap, which is typically found at the base of trees. It is not edible, although some birds(?) appear to have taken pecks out of it.

The final picture, taken recently, is a rather disgusting mess.
