Hericium coralloides can be found as a solitary clump or in clustered clumps on dead hardwood logs and stumps, sometimes in huge patches that can be seen from quite some distance.  It is recognized by its short (mostly about 1 cm long) spines, and the fact that the spines hang in rows along delicate branches. It is saprobic and possibly parasitic; growing alone or gregariously at summer and autumn.  The fruiting body can be  8-30 cm  in diameter, fleshy, white at first, light brown or yellowish with age, a few main branches arising from the narrow base, every main branch sending forth numerous smaller branches, on which dense and crowded spines hang in rows.
