It has a somewhat swol- len base and a long tapering cell (Fig. 3). The endospores are form- ed in the apex of this terminal cell and are pushed out of the rup- tured end by the growth of the unfragmented protoplasm of the base. They are hyalin, thin-walled, oblong to linear 10-25ux4-5u. The second kind of spores formed are the chlamydospores (Figs. 4-6). These are thick-walled dark brown bodies, bor

These are thick-walled dark brown bodies, born on the same mycelium as the endospores, and average from 20-50uxl0-18u, and correspond to the Torula stage of Berkeley's classification.
