a brownish -yellow colour. The foliage is very much distorted when 

 attacked by this parasite, which has a facility for spreading rapidly. 



Hitherto it has not been demonstrated that there are associated with 

 this species, as with many others, a Uredo form and a Puccinia form, 

 but it appears to be complete in itself. 



It has been found, besides Great Britain, also in France, Italy, 

 Germany, and Belgium. 



Pick off affected leaves and spray with copper solution to destroy 

 scattered spores.

Another cluster-cup (.Mcid. leucospermum) with whitish recidiospores 

 and the accompanying rust (Puccinia fusca) is found on Wild Anemone. 



ANEMONE PEZIZA. 

 Sclerotinia tuberosa (Hedw.). 



It has long been known that certain long-shaped bodies, resembling 

 Anemone roots, are to be found amongst the roots of the Wood Anemone, 

 and are called sclerotia, which represent a kind of compact fungus

mycelium. It is more than probable that they were originally true 

 Anemone roots converted into sclerotia, as the grain of Rye is changed 

 into ergot. In 1893 evidence was given (Gard. Chron. p. 75) that these 

 sclerotia have appeared also amongst garden Anemones. 



In form and size they resemble the rhizomes of Anemone, but are
