Pseudocolus fusiformis
This bizarre stinkhorn mushroom was found in September
near a lake in an area that remains damp even during dry
weather.  About three inches tall (7.5cm).
Alien.
Pseudocolus fusiformis emerges from a soft, egg-like structure
that forms from white mycelia that runs through the soil.
This fungus decomposes organic matter.
Thank you.
Spores are produced within a gleba that forms as a sticky
green-brown liquid at the tip of the fungus. This spore mass
has a foul odor that attracts flies and other insects which
help to disperse the spores.
It's all about reproduction;
(mushrooms=reproduction).
