ZEcidiospores on Tussilago farfara, June and July; October 
and November, 
Teleutospores on Foa trivialis, pratensis, nemoralis, and annua, 
but rarely on the latter, July and August, October to December. 
BIOLOGY. — Schréter states that between the uredospores are 
numerous stiff, capitate paraphyses. The teleutospores germinate 
after a very short period of rest, and produce generally two crops of 
zcidia in spring and autumn. In 1882, I found the zcidiospores 
produced the ‘uredospores on Poa annua in ten or twelve days. 
Puccinia caricis. (Schum.). 
A:cidiospores—On roundish yellow spots on the leaves, and elon- 
gated swellings on the stems, causing much thickening and 
distortion. Pseudoperidia flat, broad, with torn white edges. 
Spores subglobose, very finely verrucose, orange-yellow, 15- 
25 in diameter. 
Uredospores—Sori small, brown, linear, often confluent in long 
lines, Spores ovate or elliptical, yellowish brown, echinulate, 
20-30 X 15-25. 
Teleutospores—Sori dark brown, linear, often confluent in long 
lines. Spores elongate, oblong, or clavate, persistent, apex 
truncate or rounded, much thickened, base attenuated, smooth, 
brown, 40-70 X 14-20. Pedicels short, brownish, persistent.
