## Description

White milky mushroom (Calocybe indica) Milky mushroom (Calocybe indica) can be grown on wide range of substrates as in case of oyster mushroom. It can be grown on substrates containing lignin, cellulose and hemicelluloses. Substrate should be fresh and dry. Substrates exposed to rain or harvested premature (green color) are prone to various weed moulds which may result in failure of the crop. It can be grown on straw of paddy, wheat, ragi, maize/bajra/cotton stalks and leaves, sugarcane bagasse, cotton and jute wastes, dehulled maize cobs, tea/coffee waste etc., However cereal straw (paddy/wheat) easily available in abundance, is being widely used. Straw is chopped in small pieces (2-4cm size) and soaked in fresh water for 8-16 hours. This period can be reduced when pasteurization is to be done by steam. Main purpose of soaking is to saturate the substrate with water. It is easier to soak if straw is filled in gunny bag and dipped in water. Pasteurization The purpose of pasteurization is to kill harmful microbes. This can be achieved in two ways. Hot water treatment Water is boiled in wide mouth container and chopped wet straw filled in gunny bag is submersed in hot water for 40 minutes at 80-90C to achieve pasteurization. This is very popular method particularly with small growers. Steam pasteurization Wet straw is filled inside insulated room either in perforated shelves or in wooden trays. Steam is released under pressure from a boiler and temperature in side substrate is raised to 65C and maintained for 5-6 hours. Air inside the room should be circulated to have uniform temperature in the substrate. Sterilization Substrate is filled in polypropylene bags (x45cm, holding 2-3 kg wet substrate) and sterilized at 15 lb psi for 1 hour. Once pasteurization/sterilization is over straw is shifted to spawning room for cooling, bag filling and spawning. Spawning and spawn running Spawning methods are similar to that mentioned in
