1832. Fries, Icon. p/. 786. f. 1) doubtless refers to the same 
plant and I have a suspicion that Polystictus arcticus Fr. is also a 
synonym, since plants at Kew collected near Carlton in May, 
1858, are only grayish zonate forms of F. roseus. The actual 
types of P. arcticus I have not seen. 
A few of the collections examined are here listed: Finland 
(Karsten), Canada (Macoun, Dearness), Maine (Miss White), New- 
foundland (Waghorne?), New Hampshire (Minns, Underwood), 
Ohio (James), New Jersey (Ellis), Colorado (Bethel, Pammell), 
West Virginia (Nuttall), Washington (Piper), Florida (Calkins), 
Nebraska (Kennedy), South Carolina (Ravenel), Alabama (Peters), 
California (McClatchie), Connecticut (Underwood), Georgia (Un- 
derwood).

Many other specimens have been examined, but the above- 
mentioned are sufficient to show that the plant is of wide distribu- 
tion. It is particularly injurious to various species of coniferous 
trees.
