clavate, terminal appendage very constant in its form and dimen- 
sions, the axis of which coincides with that of the primary spore, 
and usually exceeds it in length. While these terminal appendages 
are developing, subterminal buds begin to appear about the base of 
each, normally four in number, less often two or three, which form 
a whorl of threadlike, divergent, slightly tapering appendages, 
rigid, straight or usually somewhat curved, and two to three times 
as long as the terminal ones. The origin of these subterminal

appendages is often distinguished at maturity by a slight swelling, 
more or less clearly visible between the body of the primary spore 
and the base of the terminal appendage. Asa result of the forma- 
tion of these appendages, the primary spore is left nearly empty 
and is usually seen to be traversed by a single strand of protoplasm, 
while the terminal appendages, as they mature, become filled with 
dense‘refractive contents. These terminal appendages, moreover, 
evidently become the functional spores, since they readily separate 
from the empty primary spore, carrying with them the whorl of
