ENTOMOSPORIUM 



453 



Sorauer has described an ascigerous fungus he called 

 Stigma tea mespili, which occurred on dead leaves along with 

 Entomosporium, and which he considers as being the higher 

 form of the last-named fungus. He offers no cultural 

 evidence, however, of this supposed relationship, which thus 

 rests only on juxtaposition of the two. 



The black perithecia are flattened and have an imperfectly 

 formed mouth. Spores several-celled, the minute, lateral cells 

 springing from the median septum, very small, lateral, and 

 terminal cells each terminated by a slender hyaline hair,

Spraying with Bordeaux mixture checks the spread of the 

 disease. The dead, diseased leaves should be burned or 

 buried, the diseased shoots should also be cut off. Duggar 

 has the following remarks on this fungus. In the nursery the 

 principal damage is done to seedling pears, and further injury 

 is usually to be attributed to the leaf-spot, Septoria piricola. 

 As previously mentioned, the budded stock is much less 

 frequently affected by the leaf blight, Entomosporium 

 maculatum. Seedling pears throughout the State, and 

 generally throughout the country, suffer seriously from it. 

 The youngest foliage is first affected, and often the leaves
