The Lemon Mushroom

Several years ago my mother bought a potted lemon tree and kept it out on the back porch. One day, she was surprised to notice a ripe, yellow, new-fallen lemon lying in the dirt in the pot. There were some small lemons growing on the tree, but they were green and much smaller than the one that had fallen, and that night when I was over for dinner she mentioned it to me.

Curious, I went outside to investigate the prodigious lemon. I squatted down to examine it, then poked a finger at it, and only then did I realize that I was looking at the cap of a mushroom and not a real lemon. Regrettably, I did not have the presence of mind to take a picture. The resemblence was truly uncanny. The photo I've included here gives an idea, perhaps, of how this mushroom, which is lepiota lutea, could be mistaken for a lemon in terms of color and general shape, but the one I saw in the flowerpot that morning was much more convincing.


At the time, I was astounded, convinced this was a deliberate evolutionary strategy by the mushroom--growing at the bases of trees and mimicking fallen fruit in order to trick herbivores into eating them and thus spreading the spores in their stool. As it turns out, lepiota lutea is commonly known as the "yellow houseplant mushroom" because it commonly turns up in all kinds of potted plants, for some reason. So expert opinion is against my hypothesis which, as the old Time-Life Books commercial used to say, is "dismissed as coincidence." But part of me still wants to believe.

Is it edible? Tasty?

Most websites classify it as poisonous or toxic, unfortunately. They might all be wrong, of course, but who wants to risk it and find out?

Hmm, I guess I'll just have to stick with licking the toads I find in my backyard. ;)

Just don't lick any of the brightly colored ones.
