2 days before harvesting, stop spraying water on the mushroom body, the mushroom cap is not put in bud within 4 cm in diameter, and the surface is light brown with fiber scales, and the mushroom membrane has not been broken, so it is suitable to pick it in sunny days. Hold the mushroom handle by hand and take it out, scrape off the scales of the mushroom cap and the sediment of the mushroom handle with bamboo pieces, cut off the mushroom feet with stainless steel scissors, clean it once, and put the mushroom pleats upward on a drying mat or bamboo screen for 3-4 days.
