No problem
1) Liquid culture
put 1 part honey with 100 parts of water in a mason jar. Also, put 2 or 3 small pieces of broken glass in it With the lid on loose (not turned close), autoclave for about 45 minutes.
2) Contam free mycelium
In a airflowfree space ( I made a glovebox by making two holes for my hands in a plastic curver box and just spray the inside like mad with a bleach/water solution (about 5/95 max). Then, in that space, I would cut a truffle in half using a sterilized knife of scalpel. Then, from the inside of the truffle, a spot which was completely inside and so is not covered with airborne spores, I would cut a small piece of mycelium. That piece I would quickly put into the jar that I let cool down to room temp first.
Mycelium will now start to grow. Shake every few days, the broken glass will cut up the mycelium and cause it to spread quicker. After about two weeks, you can suck a syringe full of cloudy liquid and use that to innoculate more jars.
Brew posted an alternative recipe for a liquid culture recently but I've no time to look for it now.
