lose, 10-14 fx in length; conidia not observed but spores said to 
germinate in situ. 
Hosts: Nuphar advena , Conn., Ill., Mass., Wise, (type E. cas- 
taliae) ; Eymphaea odorata , Conn., Mass., Ohio ; JSh. reniformis , 
la., Ill., Wise, (type E. castaliae) ; JSTymphaea sp., Ia., N. J., Ohio. 
This species was originally described from India by Cunningham 
and made the basis of a new genus because the spores are formed 
terminally in the branches of the mycelium and because of certain 
features in the germination of the spores. While this is one of the 
most distinct species of Entyloma, it probably does not deserve sepa¬ 
rate generic rank. Davis regards the American specimens as dif¬ 
ferent from the Indian because of certain supposed differences in 
germination. The writer believes, with Setchell, that they are the 
same. Both Cunningham and Davis described the germination of 
the spores. Literature : 40, 43.

Host: Sagittaria variabilis. Ill. 
Sori in various parts of the host, generally in the leaves rather 
permanently imbedded in the tissues : spore balls without a distinct 
cortex of sterile cells , conspicuous, composed entirely of fertile cells 
or with some sterile parenchymatous cells ; spores hyaline or yellow¬ 
ish, rather firmly united, of medium size, similar to those of Enty¬ 
loma ; germination similar to that of Entyloma. 
This genus connects Entyloma with Doassansia. It is distin¬ 
guished from the former by the possession of definite spore balls 
and from the latter by the absence of a definite cortex of sterile 
cells. Very often, however, remains of the ungelatinized mycelial 
threads surround the spore balls as a sort of false cortex. Like 
Doassansia the species inhabit hosts growing in very moist situa¬ 
tions. The only species, three in number, that have been described, 
are from North America.
