Abstract
A bin for mushroom culture for cultivating mushrooms such as shiitake that comprises upper half bin 2 and lower half bin 3 so arranged as to be able to elongate and contract by sliding upward and downward when fitted. Fitting part C of upper half bin 2 and lower half bin 3 is so arranged as to form a ventilating route F connecting the inside and outside at an elongated position P2 compared with the most contracted position P1. Thereby, ventilation is performed through ventilating route F and carbon dioxide, which is heavier than air, is exhausted.
