Netted stinkhorn, wood witch
Stinkhorns are about as unusual as fungi get, and that is more than unusual enough for me. They are North American natives.
Identification: Whoever coined the name "stinkhorn" wasn't kidding—these can clear out a room. They smell like rotting meat, attracting flies which pick up and distribute some of the spores. Flowers, of course, use a similar strategy to achieve pollination (thankfully relying mostly on scents that are attractive to people), but very few fungi are able to do this. Mature fruiting bodies are 1½-6" (4-15 cm) in height. The caps of stinkhorns are black to olive-brown, oval in shape, slimy, pitted (like morels), with a white ring at the top. The overall effect is phallic. A netlike veil or skirt emerges from under the cap. The veil may appear attached directly to the stalk, or hang loosely around it. Here is a time lapse movie of the mushroom's fruiting cycle.
