 on various species of oak, hickory, and maple. 



"Of the fleshy forms that were eaten, the following might be 

 mentioned: Chanterel Chantarelliis, Craterellus cornucopioides, 

 Lycopfrdon cyathiforme, L. gemmatum, Cortinarius semisan- 

 guineus, Vaginata plumbea, Lactaria volema, L. corriigis, Hyd- 

 nuni repandum, Boletus bicolor, Pluteus cervinus, and Hypo- 

 myces lactifluorum. Those specially avoided where species of 

 Venenarius and brilliant clusters of Clitocybe iUudens." 



"One of the most interesting observations was made at Lynch- 

 burg at the corner of Tenth and Harrison Streets. Here stood 

 an English Walnut tree over a hundred years old, which measured 

 seven feet in circumference and about sixty feet in height, and 

 had borne quantities of good nuts until about 191 5. Since 

 then, however, the nuts had been diseased and for the most part 

 worthless. Upon closer examination, some of the green fruits 

 hanging on the tree were seen to be partially blackened, while 

 many entirely blackened and decayed fruits were on the ground. 

 This walnut blight. Bacterium juglandis, has been known since 

 1900 On the Pacific coast, where it is considered a most serious 

 disease and one not amenable to treatment." 



"Dr. Pennell gave a resume of the work done by the Field 

 Committee in connection with the summer's field excursions. 

 He pointed out some of the difficulties of the situation and 

 urged a more hearty cooperation of the members of the club in 

 the future. The club voted to refer the questions to Dr. Pennell 

 with the request that he make further recommendations for 

 consideration at the Annual meeting." 



"Dr. Rydberg presented some notes on Philotria. In the 

 eastern species, the stamiate flowers have been described as 

 having oblong or elliptical petals and break loose from the 

 short pedical to float on the surface during pollination. Mr. 

 R. Hitchcock of Ithaca had sent in some specimens collected in 

 Lake Cayuaga, in which the petals are narrowly linear and the 

 pedicels elongate so that the flower reaches the surface before 

 it breaks loose. In these respects the specimens agreed with 

 P. iowensis Wylie, which hitherto had been found only in Iowa
