19 w; pedicels very deciduous. 
On Chrysosplenium aliernifolium, C. oppositifolium. Not 
common. End of March to August or September. (Fig. 162.) 
The two kinds of spores are similar in form and function to those of 
P. Veronicarum ; forma persistens consists of spores which germinate 
as soon as mature, forma fragzlipes 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.
