REPORT OF THE STATE BOTANIST FOR I924 65 



The interesting fact in connection with this is that in the type 

 material of Doctor Peck's Phoma Populi, in some of the 

 same perithecia is found a Phacidium, which so far as the description 

 goes is referable to Phacidium Populi Lasch. The asci 

 are about 30 x 8 /a, fairly large for Phacidium, and the other char- 

 acters are satisfactory for the species. 



The Phoma described by Doctor Peck is without doubt the conidial 

 stage and may be designated as Dendrophoma Populi (Peck) 

 Dearness & House, comb. nov. Doctor Seaver* retains the 

 name Phyllosticta maculansE. &E. for this species, with 

 Peck's prior name, Phoma Populi, given as a doubtful 

 synonym.
