O. Pycnia unknown. 
III. Telia mostly hypophyllous, circinating in groups 2-8 mm. across, crowded, often 
confluent, round, 0.2-0.5 mm. in diameter, early naked, pulvinate, cinnamon-brown becoming 
cinereous from germination; teliospores oblong or clavate, 15-19 by 31-45 p, rounded above, 
rounded or narrowed below, not or slightly constricted at septum; wall golden-brown, thin, 
1-1.5 yw, thickened above, 4-12 », smooth; pedicel colorless or slightly tinted, up to 19 » long. 
This species is correlated with Dicaeoma hieraciatum (Schw.) Arth. & Kern, the telial 
characters of the two species being essentially the same, and the host of the short-cycled 
species being the same as one of the aecial hosts of the heteroecious species. .

DOUBTFUL SPECIES 
Puccinia SEPULTA Berk. & Curt. Proc. Am. Acad. 4: 126. 1860. “On leaves of 
Ficus ?”’ [Island of Omotepe] Nicaragua [March 18, 1856], C. Wright. ‘The host bears 
a general resemblance but doubtless does not belong to the Malvaceae; the rust somewhat 
resembles Micropuccinia heterospora (Berk. & Curt.) Arth. & Jackson. 
PUCCINIA SUFFULTA Berk. & Curt. Grevillea 3:55. 1874. ‘‘On leaves of some unde- 
termined plant,’”’ Catoosa Springs, Georgia, Ravenel. The host of this collection has not yet 
been identified. The type specimen in the Kew herbarium shows the rust to be a species of 
Micropuccinia similar to M. maculosa (Schw.) Arth. & Jackson. 
FORM-GENERA 
Species whose life-cycle is not known, or is not readily assumed from 
related forms, and which can not be placed with confidence in the preceding 
genera, are here grouped under generic names that have long been in use, 
and have come to stand for certain definite characteristics. These genera do 
not represent the whole cycle of development, and are not based upon type 
species. 
Telia present, sometimes accompanied by uredinia, but without pycnia or other 
spore-forms; teliospores free, pedicelled, with more or less of the pedicel 
remaining attached to the spore, smooth or verrucose. 
‘Teliospores one-celled. 1. URomyces. 
Teliospores two-celled. 2. Puccinia. 
Uredinia present, occasionally accompanied by pycnia or aecia, but without telia; 
urediniospores 1-celled, readily falling from the pedicel exposing the hilurn, 
echinulate, or in a few species verrucose. 3. UREDG. 
Aecia present, sometimes accompanied by pycnia, but without other spore-forms; 
aeciospores l-celled, catenulate. 
Aecia having peridia. 
Peridia cupulate or less often cylindric, on angiospermous hosts. 4, AECIDIUM. 
Peridia cylindric or bullate, on gymnospermous hosts. 5. PERIDERMIUM. 
Aecia having no peridia. 6. CAEOMA.
