There are 8 pairs of feet (3 pairs near the head, 4 pairs in the middle and 1 pair near the tail), only the 4 pairs of feet in the middle are conspicuous. The head is reddish-brown and the tail looks like the tail of a silkworm.Its texture is fragile, easily broken, and the cross section is slightly even, yellowish-white with dark brown V-shaped clefts.

The stroma is deep brown to brown, thin and cylindrical, 4-7cm long,3mm in diameter, with fine longitudinal wrinkles and the upper part is slightly swollen above. The texture is soft and the cross section has whitish fibers.

Cordyceps has a fishy odor (like that of straw mushroom) and slightly bitter taste.
