Spots orbicular, scarcely thickened, reddish purple, sometimes 
stained with yellow; peridia short, crowded, generally with a small free 
central space; spores orange, subglobose, small, .0005 in. in diameter. 
Not unfrequently a reddish purple dash extends from the spot +o the 
margin of the leaf. The cups sometimes occur sparingly on the upper 
surface of the leaf. The free central space appears umbilicus-like, and, 
when present, is a noticeable feature.—Peck, Rep. N. Y. State Mus.,

4H. sambuci, Schw. 
Hypogenous. Spots conspicuous, yellow, swollen; «cidia 
circinate or more often densely and irregularly crowded, short, 
deeply split and recurved; spores subglobose, epispore thin, 
minutely tuberculate, 18-21 «; spermagonia very few, in the 
center of the spots on both sides of the leaf. 
On Sambucus Canadensis: Pulaski, May 5, 4498, 4497; 
May 8, 4560; McLean, May 31, 4859 (undeveloped), June 1, 
4890 (undeveloped ). 
On the young stems the excidia often occur in large dense 
clusters with much distortion of the host. 
ZK. diodiee, Burrill. 
Hypophyllous, on the cotyledons and rarely lower leaves. 
Spots distinct, small, greenish brown; ecidia few, in little ir- 
regular clusters, small, short, border little or not at all recurved; 
spores subglobose or elliptical, epispore rather thin, tuberculate, 
17-21 by 21-80 u; spermagonia rather numerous, scattered, 
above, not found on many of the spots. 
On Diodia teres: Johnson, May 13, 4661, May 16, 4700. 
This may be the ecidium of Uromyces spermacoces, which 
grows on the same host.
