Marssonina rhabdospora (Ell. & Evht.) Magn. Both specific 
names were published in 1893 but Peck’s description probably 
was issued later in the year than Ellis & Everhart’s. 
As I see it the fungus known as Gloeosporium trifolii Pk. 
develops, when perfectly formed, which often it is not, a definite 
pycnidial wall and the sporules, when mature, have a median 
septum. Occasional sporules develop 2-3 septa as is so fre¬ 
quently the case in Ascochyta. I have not had the opportunity 
to bring them to germination to see if they then become tri- 
septate as is the case in Stagonospora dearnessii Sacc. on Tri- 
folium repens. What appears to be a state of this, probably 
immature, has been collected with sporules but about 8 x 2 y 2 ji f 
continuous and what is possibly a spermogonial or microconidial 
state occurs frequently with sporules 4-8 x l-l^/q continuous. 
In this form the distal portion of the pycnid'ium is imperfect 
and it is much like the fungus on Medicago known as Sporonema 
phacidioides Desm. 
Specimens of Ramularia ionophila Davis collected at Long 
Lake in 1915 show that the spots become light yellowish brown 
with the death of the included leaf tissue and that the conidia 
are often catenulate. The spots are usually 2-5 mm. in dia¬ 
meter and the limiting veinlets sometimes give the appearance 
of a narrow colored margin. It was confined here, as in the 
type locality, to the single species of host, Viola canadensis. 
When well developed Ramularia nemopanthis Pk. is of the 
Ovularia type, the conidia being continuous, catenulate, 7-15 x 
3—6/a. 
In “Notes” I: 89-90 it was noted that Ovularia asperifolii 
Sacc. var. lappulae Davis seems quite similar to var. symphyti- 
tuberosi Allesch. Jaap has raised the latter to specific rank 
and referred it to Ramularia because of occasional septate con¬ 
idia (Ann. My col. 14: 41). When conidia are borne in chains 
the proximal members are usually longer than the distal and 
sometimes septate. I take it that the septum is due to a fail¬ 
ure of the abstriction process which becomes less active toward 
the base of the chain. In such forms the distinction between the 
genera is difficult to hold. I am inclined to think that it would 
be better to include in Ovularia only species that bear ovoid 
conidia singly.
