.05" per year, and the number of growth layers agreed in 
number exactly with the record. | 
PATTERSON, MRs. F. W.: Species of Taphrina parasitic m 
Populus.—American mycologists formerly referred to Tajh- 
rina aurea specimens occurring on ovaries of Populus tremi- 
Joides and other hosts. It has been shown, however, that the 
name T. aurea belongs only to the form on leaves, which has 
not been known heretofore in America. The form on ovatits” 
was then supposed to be identical with Johanson’s 7. rhisoph-— 
ora but from this it now proves to be quite distinct and easily 
recognized by size of asci as belonging to 7. Fohansonti Sader 
beck. A form differing but slightly from T. aurea has now . 
been found also in Iowa, parasitic of several species of Popu- : 
lus planted from Europe. j
