These are the sizes I have, plus a wedge from a plate which would just get stuck in a sterile bag, heat sealed and put in an envelope. I realize this might seem like a giveaway but I had seen a few other similar threads so hopefully this isn't out of protocol.
Next image is a collection of some yeast and a ton (20+strains) of edible fungus which I also have if anyone is interested although some of them take years to actually get to fruit if at all. The last is the dirty glovebox where the magic happens. This was right after a long plating session so pardon the filth.
