Hymenium inferior, bearing awl-shaped Spines, distinct at the base. Fries.
In this genus the spines proceed from an even surface, not folded or wrinkled, and are covered with the spore-bearing surface.
The forms are extremely variable, the type of the first section, H. repandum, being easily mistaken for one of the Agaricaceæ until examined, the stem being nearly central and upright, while in other forms it is lateral or absent. Some are dimidiate (as if part of the pileus had been removed and the plant attached by the remaining portion); the lower forms are resupinate.
