The paddy straw mushroom is grown on rice straw beds and picked immature, during the button or egg phase and before the veil ruptures(Photo 1). It is found in woodchips, rich garden soil, compost piles and, in the Pacific, on decaying trunks of fallen sago palm and empty fruit bunches of oil palm. They are often available fresh in Asia, but are more frequently found canned or dried in countries where they are not cultivated.
