No. 5.] USTILAGINEZ OF CONNECTICUT. 37 
Entyloma Nymphze (Cunn.) Setch. Figs. 18, 33. The 
sori occur in the leaves, forming yellowish, or with age reddish 
brown, variable, usually irregular areas most prominent on 
the under surface. The hyaline spores are ovoid to subspheri- 
cal, usually distinctly apiculate, and with remains of hypha as 
an appendage at opposite end, smooth or, under an immersion 
lens, very minutely verruculose, 10-14 in length. Conidia 
have not been found, but the spores germinate in situ. 
Hosts and Distr.: Nuphar advena, New Haven (Setch- 
ell) ; Nymphea odorata, Ledyard (Setchell) ; Westville, Sept. 
2, 1902, Oct. 3, 1904. 
The appendaged and apiculate spores easily distinguish 
this species from any other. Fig. 33 shows the sori on a por- 
tion of the leaf of Nymphea odorata. 
Doassansia Cornu. 
The sori occur on various parts of the host, usually in the 
leaves, and are rather permanently embedded in the tissues. 
The spores are united into large, permanent spore balls; these 
consist of a distinct cortical layer of sterile cells, with the spores 
entirely filling the interior, or limited to one or two layers be- 
neath the cortex, while the interior is filled with sterile cells 
or threads. The spores are hyaline or yellowish tinted, smooth, 
and of small to medium size. Figs. 19, 22, 29. 
Our knowledge of this and the next genus is largely due 
to the investigations of Professor Setchell of the University 
of California, but at one time a resident of this state, where he 
collected part of the material with which he worked. The 
species occur chiefly on plants growing in moist situations, es- 
pecially on the Alismacee. Of the 24 species described, 10 
occur in North America, and 5 in Connecticut. They are of 
no economic importance.
