5-celled, 5 to 64 Xx 8-16m, not constricted at the septa; and a few of 
the muriform type, 5X Ion. 
It will readily be seen from these characters that the form belongs 
to the Hyphomycetes, and in this group to the “series” Tubercu- 
larie dermatiez, “section”? Phragmosporae. Further than this its 
identification presents many difficulties. While a large majority of 
the conidia are horizontally septate, and hence must be classed under 
Phragmosporae, a small number have a longitudinal septum, but 
owing to the fact that they are borne in chains the fungus must belong 
to the genus Trimmatostroma. A careful examination of the litera- 
ture of the subject fails to show any reference to anything of a similar 
form upon any coniferous tree. 
Although, so far, the only hosts upon which this species has been 
found are Adies alba and Abies balsamea, it is very probable that the 
Spruces (Picea) are not immune. Further search will be made in the 
hope of discovering a more mature stage of this form.
