stinkhorns in my lawn

Stinkhorns frequently bewilder people by popping up in lawns, thrusting their slime-covered tips into the world within a matter of hours. They have been much maligned over the years, probably because--well, because they stink and they often look like penises (human, canine, or alien). Unlike other mushrooms, the stinkhorn distributes its spores by applying an odorous, spore-thick slime to its tip, which flies and other insects are attracted to. The flies then carry the spores to other places.
