Stinkhorn smell: flies help move the spores

Stinkhorns use a strong odor and spore-bearing slime in reproduction. Their smell can be striking without indicating that a garden plant is being attacked.

What the source describes

NC Cooperative Extension describes flies attracted to the odor of stinkhorns. Contact with the wet, spore-containing material lets insects carry spores away. [1]

The account discusses several stinkhorn forms found in lawns and mulch beds. They can appear suddenly when conditions favor fruiting, even though the fungus was already present. [1]

What follows from the evidence

Removing fruiting bodies may reduce the immediate smell, but does not establish eradication of the organism. The source does not present fungicides as a useful solution. This ecological description is not a species-identification key or a statement that an unfamiliar mushroom can be eaten. [1]

A hypothetical distinction

Imagine a mulch bed produces a smelly fruiting body after suitable weather. The odor helps dispersal; it does not by itself diagnose root disease.
