germination was quite different from the usual form. Each 
spore gave rise, from any part of itssurface, to a single germ- 
tube, or very rarely to two, which became cut, up by a few 
transverse septa. In most cases one or more of the basal 
cells remained sterile, while some or allof the others produced 
one or two flask-shaped outgrowths each. At the top of the 
neck of the flask were formed, in each case, globular spores, 
2.5 to 3 in diameter, of which not more than one was ever 
seen attached (fig. 6). These spores were also found fallen 
from their attachments and beginning to germinate (fig. 6, 2). 
In other words, these germ threads from the Moni/ia spores 
produced precisely similar structures to those which we have 
seen to be sometimes produced by the resting mycelium at 
the surface of the natural substratum. While these spores 
can germinate without nourishment, they suffer no prelimin- 
ary increase in size. On prune-gelatine they swell and ger- 
minate as above described. Though their development could — 
not be followed through, there is no reason to doubt that it ~ 
agrees with that already outlined for this spore-form. 
n another occasion, a stout hypha in a culture on prune- 
gelatine was observed to produce, at the ends of short bran- 
ches and on slight outgrowths from its sides, long chains of
