faintly granulated, chestnut-brown, 30 — 42x21 — 27/u: epispore 



thin : pedicels hyaline, short- or nearly as long as the spore.

On Leontodon autumnalis, L. hispidus. August, September. 

 Not uncommon. (Fig. 102.) 



The teleutospores of this species are said to be more than usually 

 variable ; sometimes the sori, according to Sydow, are seated on coloured 

 spots, but more often the spots are wanting. Up to the present, no 

 experimental cultures appear to have heen carried out with this Puccinia, 

 and it is separated from P. Hieracii mainly because it is parasitic upon a 

 different genus. I have found it mostly upon old yellowing leaves. 



Distribution : Europe generally.
