(After Drefeld.) bursts the wall and scatters the spores (Fig. 360). Their dissemina- tion is thus through the assistance of water, not in the dry and dusty state common for most Fungi. Though this is the case ior the typical Mucors, tliere are many Mucorineous Fungi in which the dissemination of spores is through tire air. Tliey are found among those smaller forms which live parasitically on the larger Mucors, and frequently appear upon old cultures of these as flocculent growths attached by suckers to their sporangiophores (Chaclocladiiiiii, Piptoceplialis).
