Spermogonia , circularly clustered, of light yellowish color. 
dEcidia, circularly or irregulary clustered along the nerves of the leaves 
and petioles. *Ecidiospores, polygonal, globose, verrucose, orange yellow, 
18-35 x 16-26/*. 
Uredosori, hypophyllous ; scattered, small, roundish, powdery, cinna- 
mon-colored. Uredospores, globose, subglobose or elliptical, echinulate, 
pale brown, 20-30 x 18-25/* i germ-pores always 3, placed at the equa- 
torial region. 
Teleittosori, hypophyllous ; scattered, small, roundish, powdery, blackish 
brown. Uredospores are frequently mixed in the sori. Teleutospores, 
ovate, oblong or elliptical, apex not thick, slightly constricted at the septum, 
rounded or rarely attenuated at the base, reticulated, yellowish brown or 
chestnut brown, 24-43 x 16-25/* i germ-pore of the upper cell at the apex, 
that of the lower at 2/3 from the septum ; pedicels, hyaline, slender, as long

Hab. On Anthriscus sylvestris Hoffm. 
Honshu. — Prov. Ugo : Akita (II. & III. E. TOKUBUCIII. June 5, 1902), 
Yokote (II. E. Tokubuchi. May, 1904). 
DlSTRlB. Europe and Asia. 
Remarks. Our specimens have only two stages, uredostage and 
teleutostage. The character of these stages exactly coincides with that of 
Puccinia Chcerophylli of Europe, and there is no doubt about their identity. 
It was recently proved by O. Semadeni (2) by infection experiments, that 
Puccinia on Anthriscus is biologically different from that on Chaerophyllum, 
although there is no apparent morphological differences between them.
