Newfield, N. J. Not since found, and hence doubtful.”* The material agrees 
thoroughly with the description and so removes this from the list of doubtful

144. Cekcospoka vaeia Peck. 
On Viburnum Lentago L. 
Not common or abundant. Midsummer. 
145. Cercospoka zebeina Pass.

On Mulilenbergia Mexicana (L.) Trin. 
Common, late summer and autumn. 
147. PoLYTHEiNCiUM Trifolii Kunze. 
On TrifoUum pratense L., and T. repens L. 
Abundant on both white and red clover during the entire summer. This is 
said to be the conidial stage of an Ascomycete but is retained here as the 
perfect form was not collected and the following quotation indicates that the 
species is really not well known. “On account of the characteristics and habits 
of the mycelium and of the stroma sometimes produced, it has been assumed 
that the perfect stage would be a species of Phyllachora, and the plant actually 
bears also the name Phyllachora Trifolii (Pers.) Fckl.”t 
148. Cladospoeium Trioseti Peck. 
On Triosetum perfoliatum L. 
Not rare in midsummer.
