Dehiscence basal, mouth visible only after rupture of outer peridium .Catastoma. Peridium (outer) splitting into stellate segments Geaster. LYCOPERDON. Species of the genus Lycoperdon arc small puffballs with a some-what thickened base and fibrous rooting mycelium. The peridiumconsists of two layers. The outer, the cortex, breaks up into small,soft scales, spines, warts, or granules which may soon disappear; theinner, the true peridium, is smooth, thin, and membranaceous, andopens by an apical mouth. When young the interior of the plantsis white, soft, and firm; as they become old it changes to yellow andfinally forms a purplish brown, dusty mass, composed of spores inter-mingled with threadlike filaments known as the capillitium. Acentral columella may be formed by a portion of the capillitiumwhich extends into the upper part of the plan
