Great info. I definitely did not know about the 4,000 + sex types. You explained the geneological nature but I am wondering the evolutionary reason behind having so many different sexes. I know that mycelium network is very advanced because of it's decentralized and redundant nature. If one area of the network is broken by an animal then there are other paths. Maybe the same logic somehow applies with the sex types?
