. A handbook of cryptogamic botany. Cryptogams. BASWIOMYCETES 399 tissue, with numerous compartments. To scatter the spores the stalk elongates enormously, while it increases in thickness at the same time ; the peridium bursts at the apex, and the glebe is separated from the inner peridial membrane and ele- vated on the summit of the stalk. When the spores are scattered, the conical membrane (so-called pileus) remains with the honey- comb-like structure on its outer surface attached to the apex of the spongy stalk. In Clathrus the development of peridium and glebe agrees with Phallus, but instead of a stalk a net-like structure serves to burst the peridium and elevate the glebe. Such forms as Mitremyces (Nees ab Esenb.), Tulostoma (Pars.), Polysaccum (DC), and Sphserobolus (Tode) exhibit other and remarkable types of development. Though they do not properly fall under any of the sections dealt with, they may be regarded as more or less divergent from the Fig. 331.—Aseroe rubra Berk. Mature specimen. - The i^eridium is attached below ; the glebe is in the middle of the radiating expansion (half natural size). (From de Bary, after Berkeley.) Literature.
