This mushroom is a large whitish toothed mass. It can be identified by its tendency to grow all the spines out from branches, its short spines (less than 1 inch length) and its appearance on hardwoods. It is 3 -13 inches across consisting of branches from a more or less central core.
It grows alone or in very large groups on decaying wood especially maple, beech and birch. It is sometimes parasitic on living trees. It is seen commonly in late summer and fall. It is widely distributed and common but seems rare in Fontenelle Forest.
This species is the most widespread and common species of Hericium in N. America.It is also known as H.coralloides. It has spines along the branches. The closely related H.americanum has spines just at the ends.
