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. Slice.

Imcospermum) with whitish ;ecidiospores and the accompanying rust (Puccinia fusca) is found on Wild Anemone. Anemone Peziza. Sclerotima 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 Fig. 3.—Sci.EitOTi.viA tobkrosa, natural size ; Ascrs and Sporidia x 400. mycelium.
