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

Pick off affected leaves and spray with copper solution to destroy

Another cluster cup (JEcid. leucospcrmum) with whitish recidiospores 

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

Sclerotinia tuberosa (Hedw.). 



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

 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

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