name. CLINTON (9) and Briost and Cavara (5) also maintain 
that it belongs to that genus and call it Septogloeum Ulmi (Fr.) 
Bri. and Cav. CuxrNnrTon also suggests that Cylindrosporium ulmi- 
colum Ell. and Ev. is possibly not distinct from this species. I 
have not seen the Ertis and EverHART specimen, and admittedly 
the two descriptions are very similar, especially when one takes 
into consideration the very great differences in spore measure- 
ments recorded by various collectors of Phleospora Ulmi. STEWART 
records as follows: “As we have found them, they (the spores) 
are 3- or 4-septate, usually quite strongly curved, and measure 
34-38 X5.5-6.5 u. In no. 157 of Seymour and Earle’s Economic 
Fungi, on Ulmus fulva, the spores are 3-septate, straight, and 
measure 33.56.34. In no. 648 of Krieger’s Fungi Saxonici, on 
Ulmus campestris, they are 3- or 4-septate, strongly curved, and 
measure 49.54.74. Under the name of Septoria Ulmi Fr., 
this fungus was regarded by Fucket as the spermagonial stage of 
Phyllachora Ulmi, a synonym of Systremma Ulmi, but it was shown 
by KLEBAHN (23) that it had no connection with that fungus, 
but was the conidial stage of Mycosphaerella Ulmi, which develops 
on the dead leaves in the spring. 
CYLINDROSPORIUM ULMICOLUM Ell. and Ev.—Spots becoming 
flavous; acervuli minute, hypophyllous; conidia cylindraceous, 
45-654 uw, hyaline, multinucleate, coming out in minute white 
caespitules. Reported on leaves of Ulmus alata in Mississippi. 
In spite of the differences in spore measurements, the possibility 
has been suggested that this is not different from Phleospora Ulmi. 
SEPTOGLOEUM PROFUSUM (Ell. and Ev.) Sacc.—Spots epiphyl- 
lous, flavous; acervuli scattered, hypophyllous, large; conidia 
coming out in white cirrhi, cylindrical, oblong, granular, 3-septate, 
25-30 X6-7 uw. Reported on living leaves of Ulmus americana and 
U. alata, although it was first described on Corylus americana. 
CERATOPHORUM ULMICoLUM Ell. and Hark.—Causes small, 
suborbicular, dirty-brown, amphigenous spots with a white center, 
o.5-1 cm. in diameter, on living leaves of Ulmus fulva. Not 
from several places in the United States. 
PHYLLOSTICTA ULMICOLA Sacc.—Reported as being present in 
Wisconsin by Davis (13) who states as follows:
