Polyporaceae 



Boletus. Pileus 1-3 in. broad. Stem 1-5-2-5 in. long, 2-4 lines thick. 



Woods, swamps and open places, especially under or near pine trees. 

 New York, Peck, Clinton; Minnesota, Arthur. 



A slight subacid odor is sometimes perceptible in our plant. It 

 sometimes grows on much decayed wood. Its mycelium is white. 

 Peck, Boleti of the U. S. 



The caps, only, are good. 



B. subau'reus Pk. sub and aureus, golden. (Plate CXIV, fig-^J> 

 p. 414.) Pileus convex or nearly plane, viscose, pale-yellow, some- 

 times adorned with darker spots, the young margin slightly grayish- 

 tomentose. Flesh pale-yellow. Tubes small or medium', somewhat 

 angular, adnate or subdecurrent, pale-yellow becoming dingy-ochrace- 

 ous. Stem equal, stout, glandular-dotted, yellow without and within, 

 Spores oblong or subfusiform, ochraceo-ferruginous, 8-10x4^.. 



Pileus 2-4 in. broad. Stem 1-5-2-5 in- long, 4-6 lines thick. 



Thin woods and open places. New York, Peck; North Carolina, C. 

 J. Curtis; Massachusetts, Mississippi, G. Survey (Rep. 51). 



This plant might almost be considered a stout variety of the preced- 

 ing, but in addition to its thicker pileus and stouter stem, it has smaller 

 tubes of a clearer yellow color, and the exuding drops are yellow, not 

 whitish, as in that species. In habit it appears more like B. granulatus, 

 from which it is distinct in color. Peck, Boleti of the U.S. 



From early October, through heavy frosts and until long after No- 

 vember snows I found this species at Mt. Gretna, Pa., in 1897-1898. 

 Specimens were sent to Professor Peck and identified as this species. It 

 grew in grass on borders of woods, or gravelly ground, sometimes 

 among pine needles. Large troops of it were frequent, and tufts con- 

 taining many individuals were common. 



I regard B. subaureus as among the most valuable of our food species. 

 Its plentifulness, lateness, excellent quality will commend it to all My- 

 cophagists. It can be cooked in any way. The tubes need not be re- 

 moved. 



B. hirtel'lus Pk. slightly hairy. Pileus broadly convex, soft, 

 viscose, golden-yellow, adorned with small tufts of hairs or fibrils. 

 Flesh pale-yellow. Tubes adnate, medium size, angular, becoming
