Xylaria nigripes Fruiting Body Identity
The botanical entity is Xylaria nigripes (Klotzsch) Cooke, a fungus of the family Xylariaceae that forms hard, dark, club-shaped bodies in association with termite nests. Mycological databases treat the name as a synonym of Podosordaria nigripes. The part used is the fruiting body as recorded in the specification, and culture substrate and spores are not part of this Xylaria nigripes extract. Several Xylaria species form dark bodies sold as wuling shen, so the botanical name and the part are the identity. The fungus is known for polysaccharides, ergosterol, free amino acids including gamma-aminobutyric acid, nucleosides and small amounts of phenolics, and the water extract keeps the soluble members.
Dark, hard bodies of the genus are usually collected from or near termite nests, and their appearance varies with age.
