Polystictus® pargamenus (pergamenus”) of most American authors. 
As can be surmised readily from the list of the more 
important synonyms given above, Polyporus pargamenus has 
had rather a chaotic past history. If we discredit the mon- 
strosity named “ Polyporus prolificans” by Fries we may 
consider that Fries’ Polyporus pargamenus, described orig- 
inally, under the name in current use, from specimens col- 
lected by the Franklin Expedition on trunks of pine in arctic 
North America, is the type of the species made the subject 
*Inaccurately cited by Patouillard as “ Coriolus pergamenus Berk.”, 
and correctly given by Murrill (1906, p. 654). 
* Based on the monstrosity named “ Polyporus prolificans” by Fries 
from specimen from dead deciduous trunk in Mexico. 
* As stated earlier, the name * Polystictus ” is invalid since S. F. Gray 
in 1821 used “ Coltricia ” for the plant which Fries made the type of 
Polystictus in 1851. 
* This perverted spelling was inaugurated at least as early as 1860. 
Since its use by Saccardo it has been widely followed by American 
writers.
