Mushroom preservation via co2

******I didnt write this i just brought it here from another site*******
Many growers say that their mushrooms, when kept in air tight glass containers, will last for 5+ years. Others recommend using carbon dioxide (CO2) for long term storage, to keep oxidation of psilocybin and psilocin to a minimum.
Since most people don't have a tank of CO2 available, dry ice can be used as the CO2 source. Dry ice is frozen carbon dioxide, so evaporating it at room temperature will produce CO2. It's generally quite inexpensive...somewhere on the order of $3 for 10 lbs.
Some people have mentioned a concern that commercially produced dry ice may leave a small amount of acetone residue when evaporated. Apparently acetone is sometimes used in the production of dry ice. It's possible to just ask the dry ice source about contaminents...by asking whether it's safe to put their product in a beverage to cool it.
Assuming the dry ice is contaminant-free...
1. A small pice of dry ice can be placed in the bottom of an empty mason jar. It takes about 3 cubic centimeters of dry ice (about the size of a standard die) to create enough CO2 to fill the mason jar. 2. Mushrooms can then be placed in the jar on top of the dry ice. As long as the CO2 is pure, it's ok for the mushrooms touch the dry ice. Alternately, the mushrooms can be put in a plastic bag inside the jar so they don't touch the dry ice. 3. The lid can then be set lightly on top of the jar, without sealing it, until the dry ice evaporates completely. Don't tighten the lid until it has all evaporated or it could explode. The carbon dioxide which is released during the evaporation process is heavier than air, so it will stay in the jar while displacing the air. 4. Once the dry ice is fully evaporated, the lid can be fully tightened. 5. The jar can be kept at room temperature until it's opened. The point of freezing mushrooms is to try to slow the oxidation process. In this case there is no oxygen present, so freezing would have little effect.

Huh. That is awesomely informative. I was thinking about this but wondering how to keep it from exploding...generally I'm going for the other result . 5+ shrooms for you -_-

I know this topic is old as hell but does anyone know if this method can be utilized with fresh shrooms? As in, no preliminary drying to storing them? I'm betting heavily on "no" but I really don't know.

I tried saving them fresh in a mixture of CO2, Argon, and Nitrogen. They still got nasty and shriveled up. May as well let them dry normally, and then vacuum seal. RR

I just opened 5 jars from when I posted this and they all appear to be 100% fine 2 of the jars were made when the mushrooms were about 2/3 dry and appear to be the same as when they were stored. I personally prefer my mushrooms to be dry but not cracker dry.
