The Elegant Stinkhorn (Mutinus elegans)--one of my favorite names for a mushroom--has the pungent odor of semen, and more often than not you will smell it before you see it. It grows in leaf litter and its top is covered in brown spore-filled slime, which attracts flies.
Notice the veil remnant in the last two photos. Like Amanitas, these hatch from eggs, and the volva can usually be found in the ground at the mushroom's base (second-to-last photo). And sometimes a veil remnant can be found near the tip (last photo).
Mutinus is another name for Priapus, a Greek fertility god who had a constant, large erection.
