Notes:
Fú líng is a fungus that grows around the roots of pine trees. The part closest to the root (often sold with the root still within it) is known as fú shén (Poria cum Pini Radice), root poria (literally ""poria spirit"" in Chinese). The outer surface is known as fú líng pí (Poriae Cutis), ""poria skin,"" and the pinkish section below the skin is referred to as chì fú líng (Poria Rubra), red poria.
Product Description:
The sclerotium is spherical, spheroid, or irregular shape. It varies in size, weighing 3–5 kg. The exterior surface is a blackish brown. The outer skin is thin, rough, wrinkled, and often has earth stuck to it. It is heavy and breaks open with difficulty to leave a rough fracture that is granular or farinaceous in texture. This product usually comes in the form of thin slices, with the skin removed (this being used separately). White poria (bái fú líng) is white on the cut surface, while red poria (chì fú líng) is peach-colored. Root poria (fú shén) comes in squared slices, with the yellow root of the pine that grows through it clearly visible. Cinnabar root poria (zhū fú shén) is bright vermillion.
Quality:
Loose, brittle sclerotia with flesh that is yellow at the margins are best.

Etymology:
The name fú líng 茯苓 was originally written as fú líng 伏灵, meaning ""low-lying spirit,"" i.e., a concentration of the pine's spirit underground.
