Black Fungus (Annulohypoxylon Sp.) Liquid Culture

Description

Annulohypoxylon, sometimes called cramp balls, is a genus of fungi in the family Xylariaceae. The 27 species in the genus have a collectively widespread distribution.

The genus Annulohypoxylon was created in 2005 and contains species formerly placed in the closely related genus Hypoxylon (it is equivalent to Hypoxylon section Annulata sensu).

Species in the genus Annulohypoxylon, especially Annulohypoxylon archeri, are commonly used in the cultivation of Tremella fuciformis, one of the foremost medicinal and culinary fungi of China and Taiwan.

Tremella fuciformis is a parasitic yeast that does not form an edible fruit body without parasitizing another fungus. The species Annulohypoxylon archeri is its preferred host, so cultivators usually pair cultures of Tremella fuciformis with this species, or others in the former genus Hypoxylon.
