89. Septoeia coknicola Desm. 
On Gornus alternifolia L. f. 
Found very sparingly during the last of July. 
90. Septoeia Ceyptotaeniae Ellis & Rav. 
On Cryptotaenia canadensis (L.) DC. (Doeringia Kuntze). 
Common throughout the early summer, sometimes almost covering the en- 
tire leaf. 
91. Septoeia Caccaliae Desm. 
On Caccalia reniformis Muhl. (Masadenia Raf.) 
Fairly common during the flowering season of the host. 
92. Septoeia Dieevillae Ellis & Everh. 
On DierviUa Lonicera Mill. (D. Diervilla MacM.) 
Not abundant, seen only on July 30, 1909. 
93. Septoeia Eeigeeontis Peck. 
On Erigeron annuus (L.) Pers., and E. ramosiis (Walt.) BSP. 
Common and abundant on both hosts, especially the former. 
94. Septoeia Lactuciola Ellis & Everh. 
On Lactuca canadensis L., and L. Mrsuta Muhl. 
Common but not abundant during midsummer. 
95. Septoeia Leptostachy^a Ellis & Everh. ^ 
On Phryma Leptostachya L. 
Common during the summer and rather conspicuous. 
96. Septoeia malvicola Ellis & Mart. 
On Malva rotundifolia L. 
Rather common and plentiful during the summer months. 
97. Septoeia oculata Ellis & Kell. 
On Yernonia altissima Nutt. (V. maxim Small). 
Rather abundant during late summer. 
98. Septoeia Oenotheeae B. & C. 
On Oenothera hiennis L. (Onagra Seop.). 
One of the commonest and most abundant species of the genus, hardly a 
plant of the host escaping the ravages of the fungus. 
99. Septoeia Paeietaeiae J. J. Davis. 
On Parietaria pennsylvanica L. 
Common and rather abundant in some patches of the host and less plentiful 
in others. The infection resembles that of 8. Campanulae quite closely. 
100. Septoeia Podophyllina Peck. 
On Podophyllum peltatum L. 
Common on the languishing leaves of the host, and easily overlooked on 
account of the lack of definite spots and the resemblence of the infection to 
dying leaves.
