Gender isn’t really a fungal construct.
Where we have two traditionally recognized genders, male and female, some species of fungi can have thousands of sexes. It sounds confusing, but it’s actually helpful — with so many variations, the fungi can mate with nearly every individual of their species they meet. It must make for a wild singles night.
One species of fungi, Schizophyllum commune, really shines when it comes to gender diversity. The white, fan-shaped mushroom has more than 23,000 different sexual identities, a result of widespread differentiation in the genetic locations that govern its sexual behavior. For humans, and all animals, really, this would never fly, because we’ve evolved a very specific method of reproduction that involves specialized sexual organs to do the mating with and sex cells to carry the genetic information.
