III. Telia amphigenous, closely crowded or confluent and circinating in groups 3-8 mm. 
across upon larger reddish spots, round, 0.1-0.5 mm. in diameter, early naked, pulvinate, 
chocolate-brown becoming cinereous from germination,#ruptured epidermis inconspicuous; 
teliospores oblong or ellipsoid-oblong, 16-24 by 35-48 u, rounded or slightly narrowed above 
and below, constricted at septum; wall golden-brown, 2-3 » thick, thickened at apex into 
a colorless umbo, 4-7 », smooth; pedicel colorless, as long as spore or longer. 
This species is correlated with Dicacoma rubellum (Pers.) Arth. & Fromme, the telial 
characters of the two species being similar or identical, and the hosts of the short-cycled 
form corresponding with the aecial hosts of the heteroecious form. These facts point to 
a common origin for the two species.
