A mushroom with 23,000 sexes!

You may not have heard about the Split-gill Mushroom (Schizophyllum commune), but you really should get to know them if you enjoy diversity. This little fungus has no less than 23,328 sexes. Some even say 28,000. A lot at any rate.

Mushroom sexes are different to animal sexes – they have what we call ‘mating types’. They have two points in their genetic structure that come in different forms leading to this staggering variation. Other fungi have multiple mating types too, but this creative little mushroom might be the most diverse. More mating types means less inbreeding which means greater genetic diversity and might explain why Schizophyllum commune is doing so well. They grow all over the world, except Antarctica, and might be one of the most widespread fungi in the world.

Unlike animals, many fungi can bump a bit of their body into another fungus’s body and exchange genes. Which is sexy and convenient. For split gills, while not every combination is fertile, each mating type still has 22,960 possible mates, so the chances of bumping into someone compatible are very good. Which must make using dating apps a whole lot easier.
