Scientists are starting to unravel the sex secrets of the black truffle, that rare and expensive delicacy, in hopes of making its cultivation easier. It turns out the fungus has two different sex-like states, and both must be present to reproduce. One truffle can only be one of the sexes, and while that may not sound odd to us humans, it's very out of place in the fungus world. Fungi are usually able to reproduce asexually and self-fertilize, lead author of the paper Francesco Paolocci told The Telegraph:
"It was long assumed that the truffle was like other fungi, but we know now that it needs the help of a partner. It has members of two different sexualities, a bit like male and female."
