C, two basidia, with spores, highly magniiied. {A, B, Fig. 116) are often of large size and usually more or less globular in form. The spores are always borne in the interior of more or less regular cavities, and from these they escape by the drying and rupture of the surrounding tissues. 363. The yegetative filaments of PufE-balls penetrate the substance of decaying wood, and the soil filled with decay- ing organic matter. They are colorless and jointed, and usually aggregate themselves into cylindrical root-like masses. After an extended vegetative period the filaments produce upon their root-like portions small rounded bodies, the young spore-fruits, which increase rapidly in size and assume the forms characteristic of the different genera. 364. No sexual organs have yet been discovered, but analogy points to their possible existence upon the vegeta- tive filaments Just previous to the first appearance of the spore-fruits. The spore-fruits are composed of interlaced.
