A dozen or more specimens referable to this species were found by 

 me at Mt. Gretna, Pa., August, 1897, in mixed woods. The caps were 

 eaten and were excellent.

By a painting made by the writer September, 1885, Professor Peck 

 identified the species of which it is a picture as B. nebulosus Pk. The

Pileus chestnut-brown and darker, covered with small, low, black 

 spots; convex, often depressed in center, sharp on margin. Flesh
