the U. S. 



B. lu'teus L. yellow. PileuS gibbous or convex, covered with a 

 brownish separating gluten, becoming yellowish-brown and virgate- 

 spotted. Flesh white. Tubes adnate, minute, simple, yellow, becom- 

 ing darker with age. Stem stout, yellowish and dotted above the large 

 membranous brownish-white annulus, brownish-white or yellowish below.

Pine woods and groves. New York, Peck. 



B. luteus has an international reputation for edibility. I have found it 

 at Waretown and Haddonfield, N. J. ; in Bartram's Garden, West Phila- 

 delphia, always under pines. At Waretown it was gregarious. Pine 

 needles, sand, anything through which it grows, adheres to the glutin- 

 ous cap. It must be carefully cleaned before cooking. It is then of 

 choice consistency and good flavor.
