Polyporus alboluteus. 



This plant grows on coniferous trunks, and has been abundantly 

 collected in the Rocky Mountain region. But one collection is known 

 east of the Mississippi, viz., Peck, in the Adirondack^ (cfr. Myc. Notes, 



?. 379). Ellis saw it first and called it Fomes (sic) alboluteus (sic). 

 t is neither a Fomes, white nor yellow. As the name "aurantiacus" 

 is preoccupied, orange colored plants have serious trouble in getting 

 appropriate names, and very few of them succeed (cfr. Fomes albo- 

 marginatus (sic), Letter No. 36). As Polyporus "alboluteus" (sic) is 

 a most remarkable, brilliant plant, it is a pity it was not given a 

 suitable name.
