Fiff. 1. I.i'aves of S'iiwiii/ii Ja/c'/nfn wilh diseased spots caused by HelonieUa Sk 



Infection takes place duriii^j the months of June and Y^yy, producing 

 \'eIlow discolored spots on tlie Iea\'es. In autumn, m)-cclium is well develop- 

 ed in the intercellular spaces <ä the mesophj-11, especially in the subepidermal 

 tissues. In the next )-ear, durini;- a period extending- from the end of IMay 

 to the middle of June, the aj)'ithccia mature. 



The textiu'c and other characters of the apotb.ecia and the numbers and 

 characters of the ascospeires lead us to consider the present fungus to be a 

 species of BclonicHa. Since Saccardo established the genus Btioir.clla in 1 884, 

 about ten species ha\e been described up to the present, and they are mostly 

 saprophytes with one or t\\o excc[5tions. Our fungus differs in many respects 

 from aiiy of the species already described, inducing us to consider it to be a 

 new species.
