brown or purple spots, in small round clusters 2 — 4 mm. diam., 

 elongated on the nerves and petioles, cup-shaped, with a whitish 

 lobed revolute margin ; spores tending to become ellipsoid, 

 delicately verruculose, hyaline, 18 — 26 x 15 — 22 fx. 



Uredospores. Sori hypophyllous, on pale minute spots 

 2 — 3 mm. diam., scattered, rarely aggre- 

 gated, minute, punctiform, pale-cinna- 

 mon ; spore globose to ellipsoid, echinu- 

 late, not thickened above, brown, 25 — 

 38 x 18 — 27 /j, ; epispore thick (up to 

 3£ fi), with two (rarely three) germ-pores, 



with slightly swollen caps. Fig. 131. P. Saniculae.

at both ends, sometimes slightly thickened above and provided 



with a small papilla, hardly constricted, smooth, brown, 26 —

On Sanicula europaea. Common. iEcidia, May and June; 

 teleutospores, August — October; but I have found all three 

 kinds of spores, in sheltered places, as early as April. (Fig. 131.)
