Peck, and R. pusilla Peck, seems to extend toward the south only; 
while R. betulina Burl., В. flaviceps Peck, and В. serissima Peck 
have been reported from Long Island to the northward only. Of 
the type species from Long Island, R. anomala Peck, R. magnifica 
Peck, and R. sphagnophila Kauff. have been found only in the 
type locality. Although R. blanda Burl. has been found only at 
Cold Spring Harbor, several collections have been made in different 
localities and during different seasons. 
One of the most abundant species of Russula found at Cold 
Spring Harbor was R. Mariae Peck. It grew in woods, by wooded 
roadsides, or even in the middle of sandy unfrequented roads. 
К. pectinata Peck, although not so widely distributed as R. 
Mariae Peck, occurred in abundance wherever found. One 
species resembling R. decolorans Fr. in some respects but with the 
wounded flesh turning red then gray is identical with an un 
published new species which donc H. C. Beardslee has in 
manuscript. 
The species referred to R. obscura Romell is very probably R. 
rubescens Beards. I am more inclined to this opinion because this 
autumn I have collected this on Staten Island and have seen fresh 
specimens of it from White Plains, N. Y. In fact since I began 
critical examination of the wounds of specimens resembling R. 
obscura Romell, I have seen none the wounds of which did not 
turn red as in R. rubescens Beards. When this was described in 
I9I4 it was known only from the type locality. But since then 
it has been found in abundance around Boston, and in Newfane, 
Vermont. 
The region included between Port Jefferson and Cold Spring 
Harbor lies in the part of Long Island covered with ice at the 
Ronkonkoma stage, and the soil is of a sandy or stony loam, and 
gravel structure. The woods are composed of mixed hardwoods 
with an abundance of oaks intermingled with chestnuts. It is 
possible that the seemingly limited distribution of certain species, 
and the apparent southern or northern distribution of others is 
due to lack of extensive field work or the rare occurrence of these 
species. On the other hand the character of the soil and the 
forest types may determine the southern or northern limit of 
distribution. Except as temperature affects the forest type it is
