dance of fruit. C. sterilis and C. flava are the prevailing species in 

 Bergen swamp. Among the interesting and rare species are C. gijno- 

 crates, the typical form, and C. vaginata. 



Agaricus melleus, Valil. 

 An abortive form of this Agaric sometimes occurs. It resembles 

 the abortive form of A. ahortivus. 



Agaricus serrulatus, Pers. 

 This species is quite variable. An Agaric was found in the Adiron- 

 dack wilderness which I was at first inclined to regard as an unde- 

 scribed species, but have concluded that it is a variety of A. semdatus. 

 The pileus is grayish or whitish-gray and the stem is destitute of the 

 blackish points which belong to the typical form. It may be distin- 

 guished as ydivieiY 2^allida. 



Lactarius resimus, Fr. 

 The plant which we have referred to this species as variety regnlis 

 was observed in Day. Its glabrous margin and glabrous stem remain 

 constant. The pilei,is was obscurely zonate and the stem spotted. It 

 might, at first sight, be mistaken for L. insulsus, but the change in 

 the color of the milk would correct such a mistake. 



Russula foetens, Fr. 

 Variety granulata has the cuticle of the pileus rough with small 

 granular scales. 



Gymnosporangium macropus, Scliiv. 



Plentiful on red cedar trees about Highland Mills, Orange county, 

 and also about Schoharie. 



Septoria mirabilis, Pk. 

 This should be referred to the genus Gloeosporium. 



Septoria corylina, PJc. 

 Variety permacuJata dilfers from the typical form in having the 

 spots large, brown or reddish -brown with an arid paler center. Living 

 leaves of Corylus rostrata. Day. 



Cenangium deformatum, Ph. 



If the genus Cenangium be limited to such species as have simple 

 colorless spores, this species must be transferred to the genus Karschia. 



Hypoderma Desmazieri, Duiy. 



Specimens were found on leaves of pitch pine, Pinus rigida, while 

 they were yet on the tree and green at the base. This would indicate 

 that the fungus sometimes attacks and kills the leaves.
