33. RUSSULA OBSCURA Romell, Oefv. Sv. Vet.-Akad. Fórh. 48: 
179. 1801. 
Cold Spring Harbor, Burlingham go, 1912, Aug. 3, 1912. This 
is very possibly R. rubescens Beardslee. It is impossible to dis- 
tinguish some of the dark specimens of R. rubescens from the 
typical R. obscura. Beardslee did not describe his species until 
1914 and prior to that time no notes had been made of the flesh 
of red forms of Russula changing to red when wounded. The only 
way to distinguish these two positively is to observe the change 
in the wounds of fresh plants. 
34. RUSSULA PECTINATA Fries, Epicr. Myc. 358. 1838. 
Cold Spring Harbor, Burlingham 42, 1912. Very abundant in 
sandy soil. This is probably the species which Dr. Peck referred 
to R. sororia Fries, Bull. N. Y. State Mus. 116: 84. 1907
