Figure 450.—Lysurus borealis.
The receptacle is borne on a stalk, hollow, attenuated toward the base, divided above into arms, which do not join at their apices, and which bear the spore mass in their inner surfaces and sides, inclosing the spore mass when young, but later diverging.
The stem of the phalloid is white, hollow, attenuated downward; the arms are narrow, lance-shaped, with pale flesh-colored backs, traversed their entire length by a shallow furrow.
The egg in the center is about ready to break the volva and develop to a full grown plant. The plants in Figure 450 were found near Akron, Ohio, and photographed by G. D. Smith.
Mutinus. Fr.
The gleba is borne directly on the upper portion of the stem, which is hollow and composed of a single layer of tissue; and the plant has no separate pileus, by which characteristic the genus differs from Phallus.
