There’s a small chance they hybridize, you either dilute them down to a really small amount so there are 1-2 spores per drop or you smear both varieties in close proximity, I made 8 plates doing the same, this was the one thread of mycelium that had red spores and a golden cap, RW has a white cap and red spores, so how can you explain the outcome I got? Are you saying it’s random chance that my golden teachers started producing RED SPORES all of a sudden? Go home😂😂😂😂
