228 SUMMARY OF CURRENT RESEARCHES RELATING TO 



the head being formed of conidia in chains. It was found on the 

 fallen mericarps of Conium maculatum, and in one instance on Heradeum 

 Sphondylium. Healthy plants of Conium were successfully inoculated 

 with the fungus by depositing conidia on the stigma of the host-plant. 

 The diseased mericarp was found to be filled with a dense mass of 

 colourless hyphos. It fell to the ground when fully developed, and 

 produced conidiophores in about ten days. Only one other species of 

 Symphosira has hitherto been recorded. It occurs in Germany, and is 

 not a parasite. 



American Mycological Notes.* — F. L. Stevens records his personal 

 experience after eating a small portion of uncooked L&piota Morgani Pk. 

 The poisoning was very severe. 



AV. A. Kellerman f supplies notes on the different species of Calostoma 

 found in America. He also records the finding of large cniantities of 

 Darluca filum on carnation rust. 



Brown-rot of Swedes.^ — M. C. Potter notes the outbreak of this 

 -disease within recent years in the North of England. It is well-known 

 and has been fully described in America, where the injury has been 

 traced to the presence of a bacterium, Pseudomonas campestris. It 

 attacks the plant by the leaves or by the roots and spreads through the 

 tissues by way of the vascular bundles. The disease has been already 

 recorded in this country on cabbage ; it seems to attack any cruciferous 

 plant. Methods of avoiding infection are recommended.
