rence, especially in the submerged hyphae, while in the aerial 
mycelium simple loops and coils are common (fig. 24). The hyphae 
are unconstricted at the septa, and unbranched cells are of quite 
uniform size throughout their length. Cells bearing branches 
are swollen at the points from which the branches arise.

The conidiophores, 50-90 » in length, are in most instances 
simple branches from either a principal filament or from its branches. 
They are spindle-like, with rounded tips from which the spores 
are cut off (fig. 3). The single-celled, oblong-elliptical, hyaline 
conidia are 8-12%3.5-54 4 in size, and contain two guttulae 
(fig. 23). They collect, as they are produced, in a spherical mass 
at the end of the conidiophore. A drop of water surrounds the 
spore mass after the third spore arrives (fig. 3).
