Description


Egg: the immature fruiting body is a white to pale brown egg shaped sac, up to 10 mm diameter, encasing the stinkhorn in a gelatinous substance. The egg-like sac splits to release the rapidly expanding receptacle (fruiting body) and leaves an elongated volva at the base. Often found with several eggs growing together.

Gleba(fertile spore mass): sharply conical; to 15×10 mm; covered by an olivaceous thick slime which is cleared by visiting insects exposing a pale golden brown surface; apex perforate.

Stipe: cylindrical, narrowingtowards apex and base, hollow; 80×10 mm; spongy, dry, smooth;whiteoverall or slightly pinkish at apex;with an elongated brown or whitish volva; usually attached to several tough but fine rhizoids at the base.

Indusium: absent.

Flesh: spongy.

Smell: foetid, like rotting meat, but faint compared to other Phallales.

Spore print: olivaceous brown.

Notes: this stinkhorn is recognised by its golden brown apex covered in olivaceous slime and its white stipe with an elongated white or brown volva. It grows in litter on the ground.
