508 ARTHUR: RELATIONSHIP OF GENUS KUEHNEOLA 
(P. Maclurae, P. Cherimoliae, and P. Artocarpi), must be con- 
sidered premature and exceedingly hazardous. Many forms de- 
scribed under Uredo, which almost certainly belong under one 
of the genera here presented, must await the discovery of telia 
for further assortment. 
_UREDINACEAE (MELAmMpSsORACEAE) 
Telia laterally expanded, peaticuler or discoid, indehiscent, the teliospores one-celled, 
caten e with few spores in a chain, compacte uredinia with delicate, 
cellular peridium, with aiten tose, free or baivtecloatek paraphyses or neither, 
the urediniospores sessile, apparently produced in chains with one spore matur- 
ing at a time and falling away before the next one enlarges....... PHAKOPSORA
