With yesterday's acquisition of Black Poplar (C. aegerita) and Pink Oyster (P. djamor), I'm now up to 17 mushroom cultures in my library. About a third were purchased as liquid cultures, another third from internet trades, and the final third from mushrooms I took tissue samples from myself. Most of these have been fairly recent though, and I've only grown 5 of them to fruition, waiting for the weather to improve for outdoor grows. I have a lot of work ahead of me.
