Red Stinkhorn This mushroom truly smells much worse than it looks. After all, it's called a "stinkhorn" for a reason. It has a spike-like orange fruiting body with small pockmarks and an olive-brown, gelatinous, stinky spore mass towards the apex, which is called the gleba. The fetid odor of the gleba attracts flies. The gleba sticks to the flies as they feed on it, and the flies then mechanically spread the fungus when they land in different places. In addition, the flies further aid in spore dispersal by frantically sucking up the gleba as they can consume as much as 80 percent of their body weight in stinkhorn gleba daily! This putrid gorging upsets the fly's digestive system, which then enables the spores to quickly make their exit from the fly's hindgut.

  1. So this gleba causes fly diarrhea, that's funny as well as very clever. Posted 7 years ago
    1. Yeah - of the explosive variety. Very clever, and would be insane to get a shot of the gleba exiting the fly. Posted 7 years ago

"Phallus rubicundus" is a species of fungus in the stinkhorn family. First described in 1811, it has a wide distribution in tropical regions. It has the typical stinkhorn structure consisting of a spongy stalk up to 15 cm tall arising from a gelatinous "egg" up to 3 cm in diameter. Atop the stalk is a pitted, conical cap that has a foul-smelling, gelatinous, green spore mass spread over it.
