ring; spores subelliptical, even, .0004 to .0005 incli long, .00024 

 to .0003 broad.

Gravell}^ ground under cotton wood trees, Populus monilifera. 

 Rouses Point. September. 



Three forms were found growing together. The first and 

 most abundant has the mature pileus glabrous or slightly silky 

 on the margin only ; the second has the grayish or reddish-gray 

 pileus adorned with appressed fioccose scales ; the third differs 

 from the second only in the dark chestnut color of the pileus. 

 The veil is grayish-white and when well developed it adheres 

 partly in fragments to the margin of the pileus and partly as an 

 annulus to the stem. The cavity of the stem is very small. A 

 slight odor like that of radishes is perceptible. The species 

 belongs to the section Indusiati. The variety differs from the 

 type especially in its strongly developed veil. 



Poria attenuata Pk. var. subincarnata n. var. 

 This differs from the typical form in the paler color of the 

 pores. It grows on hemlock bark and forms small patches rarely 

 more than one inch in diameter. Alcove. September. Shear. 



Septoria Cucurbitacearum. Sacc. 

 A form of this fungus sometimes develops on the fruit of 

 squashes. It produces small orbicular whitish spots on which the 

 perithecia develop. The epidermis on these spots sometimes 

 ruptures in a stellate manner. Menands. November. 



Septoria Dentarise Pk. var. arida n. var. 

 Living leaves of Dentaria dijylujlla. Pierrepont Manor. June. 

 Spots definite, arid, whitish. Otherwise like the type.
