Coral Tooth - Hericium coralloides
It is recognised by its short (mostly about 1 cm long) spines, and the fact that the spines hang in rows along delicate branches. When young, the fungus is soft and edible, but as it ages the branches and hanging spines become brittle and turn a light shade of yellowish brown. It may sometimes form large clumps.

Unless identified by a recognised expert, a photo is required and the specimen should be examined with a microscope. In the comments box, state the key or ID method used and describe the size and identifying characters.
It grows on dead hardwood logs and stumps.
Late summer and autumn.
Fairly widespread in England, though not particularly common.
Rare in Leicestershire and Rutland.
