Bottom, 6 o'clock position I see what looks like rot. I would throw it away because mold spores can last indefinitely and come out as you age or have problems with your immune system. That's how our saprophytes cause opportunistic infections in us. Another option is to do an oil extraction and make edibles. Fungal spores are less risky passing through our GI tracts. Next time will be better! (I've been growing forever now and I keep saying that )
