This creation is a kind of mushroom space bag, which includes a space bag body, a set of rings, a cover and a foam.The space bag body is provided with a bag body and a culture medium which is arranged in the bag body.And the bag body and the ferrule are mutually sheathed in advance.And the cover comprises a top plate.An outer ring wall is extended from the outer circumference of the top plate to the outer circumference of the lantern ring.And the top plate extends an inner ring wall towards the inner circumference of the ferrule.The inner ring wall is provided with at least one inner air hole.And the height from the inner ring wall to the top plate is lower than that from the outer ring wall to the top plate.A ring groove space is formed between the outer ring wall and the inner ring wall.The ring groove space is used for holding the combined lantern ring and bag body.And the foam is arranged in the inner ring wall.And the air holes in the inner ring wall correspond to the positions of adjacent foam；Thus, the space bag has the effect of avoiding dampness and increasing air permeability.本創作係一種培育菇類太空包，其係包含一太空包本體、一套環、一封蓋及一泡棉。太空包本體具有一袋體及一容置於袋體內之培養基，且袋體與套環預先相互套合，且封蓋包含一頂板，頂板外周朝套環外周緣方向延伸設有一外環壁，而頂板朝套環內周緣方向延伸一內環壁，內環壁設有至少一內透氣孔，且內環壁至頂板之高度低於外環壁至頂板之高度，而外環壁與內環壁間形成有一環槽空間，環槽空間以供組合後之套環及袋體容置，而泡棉設於內環壁內，且內環壁之內透氣孔對應設於相鄰泡棉位置；藉以提供太空包具有避免受潮及增加透氣之效果。
