II. Uredinia hypophyllous, scattered, round or oblong, small, 0.1-0.2 mm. long, soon 
naked, or on some hosts rather tardily naked, light cinnamon-brown, ruptured epidermis 
noticeable; urediniospores globoid or broadly ellipsoid, small, 12-19 by 16-23 »; wall light 
cinnamon-brown, 1~1.5 » thick, finely echinulate, the pores 2, in the upper part. 
III. Telia hypophyllous, scattered, round or oblong, 0.1-0.3 mm. wide by 0.2-0.8 mm. long, 
soon naked, or on some hosts rather tardily naked, blackish-brown, ruptured epidermis con- 
spicuous; teliospores clavate or oblong-clavate, 12-20 by 35-50 y, slightly or not constricted 
at septum; wall chestnut-brown, 1—1.5 » thick, thicker above, 5—10 », smooth; pedicel tinted 
next to the spore, about one half length of spore. 
This species is morphologically the same as Nigredo perigynia (Halsted) Arth., except in the 
septation of the teliospores, and the two forms should eventually be united under one name. 
‘The species is similar to the two following species, D. Peckii and D. hieraciatum, but in general 
may be separated from both of them by the aecial hosts, from D. Peckii by the smaller urediniospores, 
and from D. hieraciatum by the narrower teliospores. Numerous cultures combined with field 
observations have shown the existence of well fixed races, especially the three called Puccinia Caricis- 
Asteris Arth., P. Caricis-Erigerontis Arth., and P. Caricis-Solidaginis Arth., associated with the 
aecial host-genera Aster, Erigeron, and Solidago and their close allies respectively, and to a much 
less degree associated with certain species of the telial hosts.
