central filament of the conidia-bearer supports four lateral club 
shaped branches, each of which is elongated considerably—pe: 
nearly at right angles with the central filament and with the two 
adjacent sister-branches in the same whorl. Before any who 
has arrived at.this stage the next whorl above will be seen to 
developing as filamentous outgrowths, or as projections, from th 
central hypha. 
After having assumed the club-shaped appearance just d ; 
scribed, the branch-hypha €long<tes further, becomes distinctly” 
vacuolated and swells somewhat along its whole extent in such 
manner that the points of greatest constriction are just at the ir 
sertion of the hypha, and just below the club-shaped apex. Fur- 
ther development now takes place in the terminal swollen area oF 
each branch-hypha in such a way that the extreme apex is pro- 
longed into a conical point, and four similar conical projections 
appear equidistant from each other around the equatorial region 
of the terminal swollen area. Each of these five projections thus 
formed continues its growth and behaves much as did the parent 
branch-hypha. Thus five secondary branch-hyphe are produced, 
or four, if we choose to consider the terminal projection as a con- 
tintation of the primary branch-hypha. Each of the five projec- 
tions develops a ternary five-lobed projection, and in rare cases 
each ternary lobe may develop a series of five quaternary lobes. 
In the formation of secondary, ternary and quaternary lobes of 
branches the whorled arrangement is not original, but is the re- 
sult of post-developmental compression, differing from the forma- ; 
tion of the primary branch-hyphe. In this latter case alone did 
the whorl seem to be a true whorl. The development of ternary 
lobes is usually not followed by the elongation and differentiation: 
of each lobe into a hypha and quaternary-lobe-series. This was 
noted in but one conidia-bearer among over two hundred. 
The ternary lobes (or quaternary in cases where they occut) 
are the conidial areas. The process of forming the conidia is :

Each lobe becomes swollen into a more or less spherical 
shape, and the greater part of the convex surface becomes at: first 
faintly rugose. Later it is seen to be covered with small hemi
