ANEMONE SCLEROTINIA 



(Sderotinia tuberosa, Fckl.) 



This fungus is very destructive to the wood anemone 

 {Anemone netnorosa), 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 PAEONIES 



(Sderotinia 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.
