short stalk-like base. The spores are round and measure 4-5 # 
in diameter. The mycelium is subcuticular only, not penetrating 
into the tissues of the leaf. 
TAPHRINA AUREA (Persoon) Fries. 
, | This species was collected at Columbia, S. C., May, 1889, on 
the leaves of Populus monilifera Aiton. It forms rounded, rather 
deep, open pockets which arch upwards, the asci being on the 
concave or under side of the spots. The asci are of the slender 
kind in the specimens examined, with long narrow stalk-cells. 
which penetrate far between the epidermal cells. According tO 
Sadebeck this species has hitherto been reported on P. monilt- 
Jera only from Denmark. It is also, I believe, the first recorded 
occurrence of this species in North America, the specimens which ; 
have been heretofore reported as belonging to this species in this = 
country occur on the fertile aments of species of Populus, which is 
entirely different. These specimens on the fertile aments of several 
species of Populus (tremuloides, Fremontii, grandidentata), have | 
been referred by Farlow to Zaphrina rhizophora Johanson. I have: 
had an opportunity of examining specimens from the fertile aments 
of Populus tremuloides Michx. collected at Ithaca, N. Y., by R- H 
Pettit, May 13, 1891. They are certainly Zaphrina vhisophora | 
Johanson, the asci lacking the stalk-cells, and the narrowed bas¢ 
penetrating 30-40 » in the tissue of the hypertrophied ovary.
