Amphigenous, mostly scattered amongst the aecidia, pale-yellowish. ^Ecidiospores. ^Ecidia hypophyllous, in smaller or larger groups, often along the nerves and causing slight hypertrophy, between cup-shaped and pustulate, with a whitish irregularly cut margin; spores verruculose, subhyaline, 20—28/z. Uredospores. Sori hypophyllous, scattered, minute, pul- verulent, cinnamon; spores globose to ellipsoid, echinulate, brown, 22—32 x 20—26 /i, with two (rarely three) germ- pores. Teleidospores. Sori similar, but blackish-brown; spores ellipsoid, rounded Fig. 136. P. Pimpinellae. a^ both ends, not thickened above, hardly Teleutospore, on P.

Xot common. zEcidia, May and June ; teleutospores, July—October. (Fig. 136.) Very similar to P. Ch.aeroph.ylli ; distinguished from it especially by the uredospores, which have for the most part a thicker and darker membrane with on
