• More contamination than anything else

  Hi, my name is Ron. I’m new to mushroom growing. Currently, I have some Reishi and Lion’s Mane mushrooms, but I think I have some contamination in both mushroom cultures. I inoculated some sterilized maize grain spawn 3 months ago. For the Reishi spawn(first 2 images), I thought it could be Trichoderma after reading this article (https://shroomok.com/en/wiki/Green_mold_contamination_aka_Trichoderma ). However, it does not have a similar green color, it remains the same gray even after a couple of days. It also seems to grow in distinct clusters apart from the Reishi mycelium. For the Lion’s Mane batch, I have spotted three “irregularities”: one that looks like Trichoderma(third image), something that is black and a little spotted around (fourth image), and then a black, more cloudy-looking growth(fifth). I’m sure this spawn is unsalvageable, but does anyone have an idea of what this could be? Thank you for taking the time to read this and for any suggestions.
