Teleutospores, 
hyaline, up to 40 long; occasionally 
a few one- or three-celled spores are 
intermixed. 
On Anemone nemorosa. Common. 
March—June. (Fig. 164.) 
It has been shown by De Bary and Ed. 
Fischer that the mycelium is perennial in the 
rhizome. The attacked plants are deformed 
and never flower; they bear paler and narrower 
leaves which are much thickened. The ecidia 
on the same host are not connected with this species (see Ochropsora Sorbi 
and P. Pruni-spinosae) ;, in fact they do not appear until some time later 
than the teleutospores of P. fusca begin to show,
