Sori hypophyllous, on sunken yellowish or purplish round spots, minute, pulvi- nate, brown, then with a greyish bloom, scattered or circinate and at length confluent in a thick crust; spores generally fusoid, rounded or conically attenuated above and much thickened (up to 12 /a), gently constric- ted, attenuated downwards, smooth, yellowish-brown or brown, 25—40 x 9—13/a; pedicels hyaline, persistent,. Fig. 14(). P. Circaeae. Teleutospores. about as long as the spore. On Circaea alpina, 0. lutetiana. Rather common. August— October. (Fig. 146.) The sori of this species present two different forms: the first-formed are roundish, clear-brown, solitary or circinate and confluent ; the later- formed, which appear round the others or on the stem and on the nerves of the leaves, are darker-brown and never greyish. All the spores are of the same shape, but the paler ones can germinate at once, in the sorus, while the darker ones rest until the following spring, as in P. Veronicarum. There is another Uredine on the same host, even occurring on the same leaf : see Pucciniastmm, Circaeae. Distribution : Central and Northern Europe, North America, East Indies. 71.
