Hericium ramosum is the most delicate of the three species that occur in our area. It has a loose, open branched structure, and relatively short spines which are arranged in rows except for the branch tips where they are tufted. Hericium erinaceus, more common than H. ramosum, also grows on hardwood logs, can be distinguished by an unbranched cushion-shaped base from which hang long, slender, white to cream-colored teeth. Hericum abietus has a fruiting body intermediate in structure between H. ramosum and H. erincaceus. It grows on conifer logs, sometimes forming impressive, large, white to cream-colored fruitings.
