... And the watermelon, like all gourds, is one of them: a plant cultivated only for its fruit. That appears to be a bug in the blog post. Some plants, are eaten both ways (both the fruiting body and leaves or other body parts are consumed).

With fungi we eat only the fruiting body, but nobody calls them “fruit” except in the superclass sense (“fruit of the land”)

We don't call them fruit, we call them mushroom. And they can't have fruits, as in pear tress or other angiosperm plants, because mushrooms aren't plants.

The fruiting body, which is not fruit, doesn't have seeds. They have spores, I think.
