constitute a true fructification. They are, in’any point of 
view, to be called conidia. Furthermore, the homologies of 
this form seem to be clear. Tulasne!® has figured similar 
them in the latter species and Sel. Fuckeliana. Zopf*! saw 
very similar structures on the mycelium of Chaetomtum, and 
Woronin?* in Sordaria. In all of these cases the general 
structure and mode of development of these conidia is the 
same. Tulasne found them rather sparingly produced on 
young germ-tubes developed without extraneous nourishment, 
Just as did the writer in one instance. Brefeld and DeBary 
obtained them very abundantly in cultures on nutrient media, 
which was once the writers experience. When developed 
mycelium, they are produced almost as abund- 
antly as on nutrient media. Neither of the writers mentioned 
above was able to observe the germination of these spores, 
and they Were classed by DeBary”? as ‘‘doubtful spermatia, ”
