Teleutospores. Sori amphigenous, but generally hypo- 



phyllous, small, scattered or con- 

 fluent, often circinate, roundish, 

 pulvinate, pale-brown; spores of two 

 kinds — (forma persistens) broadly 

 fusoid, strongly thickened and 

 more or less conical at the apex, 

 rounded or slightly attenuated 

 below, gently constricted, smooth, 

 very pale-brown, 32 — 46 x 10— 

 1") /n: pedicels hyaline, rather long, 

 persistent ; (forma fragilipes) ob- 

 long-ellipsoid, with a conical papilla, distinctly constricted, 

 yellowish-brown, with faint longitudinal ridges(7), 35 — 42 x 14— 

 19 fi ; pedicels very deciduous. 



On Chrysosplenium alternifolium, G. oppositifolium. No1 

 common. End of March to August or September. (Fig. 1<>2.) 



The two kinds of spores are similar in form and function to those of 

 /'. Veronicarum ; forma persisteas consists of spores which germinate 

 as -non as mature, forma fragilipes of spores which rest during the winter. 

 It is said that the latter are scarce, but when present they form smaller 

 sori which are less confluent, often solitary, and are frequently found 

 on the upper leaf-surface. Compare the two similar kinds -of spores in 

 P. Circaeae. 



Distribution: Central and Northern Europe, Eastern Asia.
