654 Murrill : Polypokaceae of North America 



molliusculus is here thrown into synonymy only after a careful 

 examination of the original specimens, which fully warrant this 

 disposition of a troublesome name. 



Specimens are at hand from Canada, Dearncss ; New Hamp- 

 shire, Miss Minus ; New York, Murrill ; New Jersey, Ellis ; Dela- 

 ware, Commons ; Pennsylvania, Barbour; West Virginia, Nnttall ; 

 Florida, Calkins ; Alabama, Benson, Underwood, Earle ; Louisiana, 

 Langlois ; Ohio, Lloyd; Missouri, Dcmetrio ; Kansas, Cragin ;

25. Coriolus abietixus (Dicks.) Quel. 



Boletus abietinns Dicks. PI. Crypt. Brit. 3: 21. pi. p. /. p. 1793. 

 Boletus incarnatus Schum. Enum. PI. Saell. 2 : 391. 1803. 

 Coriolus abietinus Quel. Ench. Fung. 175. 1886. 



A good description of this plant is to be found in the Magazin 

 fur Botanik 12 : 19. 1790, presumably written by Schrank, but I 

 hesitate to ascribe the species to him on the basis of this citation. 

 It seems quite certain that Sistotrema fuscoviolaccinn Pers. is a 

 form of the present species ; and, according to Bresadola, P. caesio- 

 albus Karst. is not specifically distinct. 



This species has been well known for a long time by reason of 

 its abundance throughout the northern hemisphere on decaying 

 wood of coniferous trees, none of which appear to be exempt from 

 its attack. Of the large number of specimens examined, the fol- 

 lowing may be mentioned : 



Finland, Karsten ; Tyrol, Bresadola; Newfoundland, Wag- 

 home; Canada, Maeoun ; New York, Shear, Undenvood, Peck; 

 New Jersey, Ellis ; South Carolina, Ravenel ; Georgia, Harper ; 

 Alabama, Mell ; Cuba, Undenvood & Earle ijjy / Texas, 

 Ravenel ; California, McClatchie ; Colorado, Bethel.
