VESSEL FOR SEED FUNGUS CULTIVATION OR BOTTLE CULTIVATION OF MUSHROOMS

摘要

A vessel for cultivating mushrooms comprises a container and a cover for the container. When the vessel is in a closed condition, air is permitted to pass into the vessel only through a porous plastics film material extending over an aperture in either the container or the cover. The film material is permeable to gas but impermeable to bacteria and microbes infectious to mushroom culture.
