on that plant. I am not certain that P. punctata lives on G. Cruciuta, 
though I think I have seen it on that host ; the two usual species on that 
Galium are P. Celukovskyana and P. Valantiae (q.v.). 
The zcidium seems to be less common than the other spore-forms : 
I have seen it on @. Mollugo, G. verum and G. uliginosum. Mesospores 
have been observed on G. palustre, G. saxatile and G. verum. On 
G. saxatedle the teleutospores were slightly larger than in the normal form, 
but otherwise identical; P. Valantiae, which occurs on that same host, is 
easily distinguishable.

Teleutospores. Sori hypo- 
phyllous, on brownish spots, thickly scattered, minute, roundish, 
on the stems linear and up to 1 mm. long, soon naked, pulvinate, 
black-brown ; spores oblong to clavate, rounded (very seldom 
narrowed) above where they are much thickened (up to 11) 
and darker, faintly constricted, tapering below, smooth, chestnut- 
brown, 85—56 x 17—25 w; pedicels hyaline, thick, persistent, 
not as long as the spore; an occasional mesospore is found.
