BOLETINUS PICTUS Pcck. 



Collected twice in considerable quantity, once in swampy- 

 ground and once on a dead locust log in low woods. 



This species has the large radiating tubes of the genus Bole- 

 tinus, and is easily distinguished among the Boletaceae by the 

 conspicuous red scales that adorn its pileus and stem. It is 

 fairly common in the woods and mossy swamps of the mountain- 

 ous regions of the eastern United States. Edible. 



Boletus americanus Peck, 



Common, especially near pines. 



This is a common and widely distributed edible species having 

 a yellow, viscid cap usually dotted or streaked with red and a 

 slender yellow stem covered with reddish brown viscid dots which 

 become black on drying. 



Boletus auriflammeus B. & C. 



Five specimens were collected on a well-drained bank exposed 

 to the sun about two hours just after midday. Dr. House after- 

 wards sent me a number of fine specimens. 



This species is of great interest, being very rare and very beau- 

 tiful. It was originally collected in North Carolina by Rev. M. 

 A. Curtis and sent by him to Berkeley, who described it. Peck 

 found one plant at Sandlake, New York, and it was also reported 

 by Beardslee from Brookside, West Virginia. The description 

 given by Berkeley is both incomplete and inaccurate, but the 

 bright golden yellow color of the pileus and stem should easily 

 distinguish it. The mouths of a few of the tubes sometimes 

 appear scarlet, especially on drying, but this character is not at 

 all conspicuous. The stem is beautifully reticulated. 



Boletus auriporus Peck. 



Occasional on banks and in open woods. 



This species may be easily recognized by its bright golden 

 yellow tubes which retain their color on drying. The cap is 

 usually reddish brown and the stem is viscid if the weather is not 

 too dry. Edible. 



Boletus bicolor Peck. 



Several times collected on banks and in thin woods.
