The Phallales are all terrestrial fungi; that is, they are found growing on the ground, and not on logs and trees. They are interesting, but too offensive to attract any but the most courageous students.

They are more common in the South than in the North, where they make themselves too conspicuous by their intolerable odour.

They are structurally different from the other pouch-fungi, the puffballs, in that they do not retain their spores in the skin (pe-ridium) until they are fully mature, but send them into the light, exposed on a quickly deliquescing jelly-like mass, the gleba.

The order may conveniently be divided into two families: family I. clathraceae:

Receptacle latticed, sessile, or stalked. Spore mass borne on the inner surface of the receptacle.

Family II. Phallaceae

Receptacle tubular or cylindric, with a cap.

Spore mass on the surface of the cap.
