66 TWENTY-FOURTH REPORT ON THE STATE MUSEUM. 
Agaricus aBortivus B. & C. 
Ground in woods and copses. Greig and Greenbush. Septem- 
ber and October. 
The lamelle are arcuate and long-decurrent in some specimens, 
nearly plane and adnate-decurrent in others. They are at first 
grayish with a flesh colored tint, at length bright flesh colored ; 
some of them are forked. The odor is like that of fresh meal, the 
taste not unpleasant. I have partaken of it without any injurious 
effects, and deem it edible, though not as pleasant as some. The 
abortive form sometimes grows intermingled with the others, 
sometimes alone.

in view of the interest he has manifested in the study of fungi.
