If you inoculated it ... incubate it to germinate the spores... they will take forever in teh fridge! !!!!!
Once you use it and want to store it.. then use the fridge...

It can be stored uninoculated and remain usable for at least 7 weeks, after colonization I would say you begin to loose viability after a few months if not stored properly...Pick up the mushroom cultivator by paul stamets, buy it through the shroomery and you get a discount....anyway, Stamets says that some cultures have remained viable for more than 20 years when stored under the right conditions, 2-3 years if it's not....

Isn't it best to transfer from a petri to a slant for storage?? A slant being beter because it has more agar for the culture to draw nutrients from whereas a petri is for short term..
This is assuming the original poster is using petris.

I would have to say....yes...but petris are more for obtaining a pure culture as opposed to any sort of storage, they dont seal well and allow contaminants in...there are ways around this....using a short half pint jar with about half the volume being agar is more than ideal.....but if it's to be any longer than 2 months in a sealed and refridgerated petri then the slant need to be involved....
did that last part sound a little racist?
