DOUBTFUL SPECIES 
Boletus undulatus Schw. Schr. Nat. Ges. Leipzig 1: 96. 1822. Polyporus undulatus 
Fries, Elench. Fung. 87. 1828. Described from North Carolina. Type not found. 
Apparently near S. galactinus. . 
Polyporus finbriporus Schw. Trans. Am. Phil. Soc. II. 4: 155. 1832. Described from 
specimens collected on small fallen chestnut limbs at Bethlehem, Pa. The type specimens 
at Philadelphia show a close relationship to S. fissz/is, but are too meager to determine the 
true position of the species without additional material.
