mostly broadly ovate, obovate or elliptical, little constricted, 
apex usually slightly thickened or apiculate, smooth or minute- 
ly roughened, 21-25 by 32-50 », commonly about 39 » long; 
pedicel hyaline, rather fragile, from less than one to one and a 
half times the length of the spore, sometimes more or less lat- 
eral, 
Spots brown and indefinite, sometimes none; sori mostly hypo- 
phyllous, sometimes amphigenous, orbicular, oblong or irregular, scat- 
tered or crowded, sometimes confluent, prominent, at first covered by 
the epidermis and then of a peculiar lead-color, blackish when exposed ; 
spores obovate or elliptical, obtuse, slightly constricted at the septum, 
minutely rough, .0012-.0016 of an inch long, .0008-.001 of an inch broad, 
the pedicel very short, colorless.— Peck, Bot. Gaz., Vol, VI., p. 228. 
On Phlox divaricata: Adams, June 80, 5358. 
The description by Peck is from specimens collected in 
Utah. During the same year, but believed to be later, DeThi- 
men sent out Century XXI of his Mycotheca Universalis, con- 
taining, with No. 32, a description, with specimens from Idaho, 
on Gilia, under the name of P. Wilcoxiana. By comparison 
of authentic specimens these prove to be specifically indistin- 
guishable, as well as those of Ellis’ North American Fungi, 
No. 1044—however, the latter bears the varietal name of 
phlogina. This last has a different nuclear spot in each seg- 
ment, and the epispore is more distinctly roughened. The IIli- 
nois specimens on Phlox are very nearly smooth, and do not 
have this round segmental spot, hence are more like the typi- 
cal specimens of Peck in these respects. They are somewhat 
more irregular in shape than any of the others, and the pedicel 
more often obliquely produced.

I. Hypogenous. Spots small, distinct, or sparingly con- 
fluent, brown; ecidia irregularly clustered or sometimes subcir- 
cinate, short, small, pseudoperidium fragile, becoming powdery 
soon after opening, spores subglobose or elliptical, epispore thin, 
tuberculate, 16-18 by 18-25 »; spermagonia few, central, above.
