PUCCINIA 



covered with large waits, brown, 30—55x15 — 2(> : pedicels 



hyaline, up t * > 40/z long: occasionally 



a few one- or three-celled spores are 

 intermixed. 



On Anemone nemorosa. Common. 

 March June. (Fig. 104.) 



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 eecidia 



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 oiP.fusca begin to show. 



Distribution: Europe, Siberia, North America.

Spermogones. In little clusters, honey-coloured. 

 jEcidiospores. iEcidia hypophyllous, in little clusters on 



roundish yellowish spots, or on the 

 stems in elongated swellings, cup- 

 shaped, with a torn whitish recurved 

 margin ; spores delicately verrucu- 

 lose, orange, 21 — 28 /x. 



Uredospores. Sori generally hy- 

 pophvllous, minute, scattered, round- 

 ish, pulverulent, chestnut; spores 

 globose to ellipsoid, echinulate, pale- 

 chestnut, 22—30 x 20—25 fi, with 

 two germ-pores in the upper half. 



Teleutospores. Sori amphigenous, small, irregularly scat- 

 tered or often circinate, pulverulent, but persistent, black- 

 brown ; spores oblong-clavate or fusoid, generally with a paler
