dance of fruit. CC. sterilis and C. flava are the prevailing species in 
Bergen swamp. Among the interesting and rare species are C. gyno- 
crates, the typical form, and C. vaginata. 
Agaricus melleus, Vahl. 
An abortive form of this Agaric sometimes occurs. It resembles 
the abortive form of A. abortivus.

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. serrulatus. 
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 variety pallida. 
Lactarius resimus, /7. 
The plant which we have referred to this species as variety regalis 
was observed in Day. Its glabrous margin and glabrous stem remain 
constant. ‘The pileus was obscurely zonate and the stem spotted. It 
might, at first sight, be mistaken for Z. insulsus, but the change in 
the color of the milk would correct such a mistake. 
Russula feetens, /’r. 
Variety granulata has the cuticle of the pileus rough with small 
granular scales, 
Gymnosporangium macropus, Schw. 
Plentiful on red cedar trees about Highland Mills, Orange county. 
and also about Schoharie. | 
Septoria mirabilis, Ps. 
This should be referred to the genus Gleosporium. 
Septoria corylina, Px. 
Variety permaculata differs 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, Pk. 
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, Dudy. ; 
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.
