Mushroom spawn is the term given to a net of fragile threads (Thallus or Mycelium), often found underground, which lives and grows on the surface of decomposing animal or vegetable matter and develops in the tissues themselves and produces mushrooms.

This subheading also includes a product consisting of mushroom spawn, not fully developed, placed in microscopic amounts on a layer of cereal grains enclosed in a compost of sterilized horse manure (a mixture of straw and horse dung).’
