Dave Rose cut this ovoid stinkhorn 'egg' in half so that we could all see the inside structure. Within the thick, gelatinous outer layer is the immature form of the fruiting body with a distinct white conic head with an opening at the apex and the spongy stem in the center. The dark material surrounding the cap is the gleba, the olive-blackish-brown spore mass. At this 'button' stage, it exhibited no particular odor, but as the fungus expands, the head is coated in a slimy layer of the spore material, which develops the strong odor of rotting flesh. The aroma entices a variety of insects from ants to flies, whose anatomical parts that have come into contact with the material, serve as convenient spore dispersal agents. Pretty clever!
