Vessels suitable for storing mushrooms [ Agaricus bisporus (Lange) Singe] at absolute pressures to 35 atm were constructed from 43 liter (1A) gas cylinders and plumbed for conducting static or continuous‐flow experiments. Neither pressurization nor gradual depressurization over 6 hr injured mushrooms. Pressure did not affect respiration, but significantly reduced moisture loss during storage. Mushrooms depleted O 2 to very low levels and showed high tolerance to CO 2 . Pressure was used to safely increase CO partial pressure (p) 35‐fold. At 0.035p, CO reduced mushroom browning but not respiration. A completely autonomous storage system with CO 2 removal and automatic O 2 , replenishment was developed.
