18 Murrill: Boletaceae of North America 



This very handsome species was collected by Frost in con- 

 siderable quantity near Brattleboro, Vermont, and is known to 

 occur sparingly also in Connecticut, New York, New Jersey, 

 Pennsylvania, District of Columbia, Tennessee, and Indiana. 

 Its favorite habitat is thin oak woods, where the light is suffi- 

 cient to enable grass to grow. Specimens collected by Sprague 

 were returned by Berkeley under the name B. alveolatus B. & C, 

 which was published by Frost with a description. Meanwhile, 

 Berkeley had decided that the plant was only a form of B. edulis 

 (Grevillea i: 36. 1872.) 



Doubtful Species 

 Boletus parvus Peck, Bull. Torrey Club 24: 145. 1897. De- 

 scribed from specimens collected by L. M. Underwood in 

 grassy woods near Auburn, Alabama. I have been unable to 

 find the types of this species either at Albany or New York.
