ANEMONE SCLEKOTINIA 



(Sderotinia tuberosa, Fckl.) 



This fungus is very destructive to the wood anemone 

 (Anemone nemorosa\ also cultivated species of Anemones. 

 The blackish sclerotium varies in form and size, half to 

 three-quarters of an inch long, and attacks the rhizomes of 

 the anemone. In the spring numerous long-stemmed, 

 smooth, dark-brown ascophores are produced. The fertile 

 portion is at first pear-shaped and closed, then funnel- 

 shaped, and at maturity expanding until almost flat. 



PREVENTIVE MEANS. Collecting the ascophores in the 

 spring checks the spread of the disease. 



DROOPING DISEASE OF FAEONIE8 



(Sclerotinia paeoniae,, Massee. 

 =Botrytis paeoniae, Oud.) 



Unsightly gaps often appear in beds of paeonies, caused 

 by this fungus. Healthy-looking plants some time before 

 the period of blooming suddenly become limp, the stem 

 droops, and within a few days the plant dies. If the stem 

 of a diseased plant is examined, a very delicate white mould 

 will be seen on its somewhat blackened and shrivelled 

 surface, just above the ground ; and at a later stage, 

 numerous minute black sclerotia are formed in the tissues, 

 both above and below ground.
