I. Hyrnenium. Voleosporium baccharidis, Cke. & Hk. 



II. Stylospores. Smooth, globose, yellow, mixed with 



III. Teleutospores. Hypophyllous ; sori few, solitary, 

 i — 1 mm. pale brown; spores large, oblong, or obovate, 

 golden yellow, constricted at the septum, epispore smooth, 

 thickened at the apex, having the appearance of being drawn 

 in and so forming small folds; contents granular or oily, 

 with large vacuoles, easily discharged by pressure, leaving 

 the colorless epispore ; |pedicel hyaline , very stout, as long 

 or longer than the spore, jjl 55 — 60x15 — 20.

 November. 3384. 



This Puccinia has been overlooked heretofore on account 

 of its minute size and pale color. It is without doubt the 

 final stage of Coleosporium baccharidis, being always found 

 together with it on the same plant — Coleosporiurn upon 

 the branches, and Puccinia upon the leaves. 



Puccinia symphoricarpi. 



I. Hymenium. iEcidium : preceding the teleutospores; 

 hypophyllous, in circular clusters of 8 — 20, on dark brown 

 or discolored spots; peridia as long as broad; spores orange. 



II. Stylospores Unknown. 



III. Teleutospores. Sori small, aggregated, covered by 

 the epidermis 1 — 3 mm. in diameter, on irregular brown 

 spots; spores oblong, constricted, brown above, paler below, 

 epispore smooth, thickened above, lengthened somewhat 

 obliquely into a finger-like process'; pedicel of the same color, 

 and lh times as long as the spore. /< 50 — 60 X 15—17.

Puccinia variolans. 



I. II. Hymenium and Stylospores. Unknown. 



III. Teleutospores. Sori solitary, oval, dark brown, 1 

 mm. in length; spores brown, oblong or slightly clavate, 

 constricted; epispore smooth, thickened above, pedicels 

 hyaline, 1 — 2 times as long as the spore, m 40 — 70 X 18 — 24.
