Wharton, Henry Thornton. "Oh Fries' Nomenclature of Colors," 

 in Grevillea, Dec. 1884. 



This consists of an examina^tion of the epithets used by Fries in 

 describing the coloration of the Agaricini," and was read before the 

 VVoolhope ^Naturalists' Field ClubV Oct. 13, 1884. Mr. Wharton enume- 

 rates only those found in the Hymenomycetes Europsei," and the list, 

 excluding reference to compound names, reaches nearly 200. His com- 

 plete list, as originally made, amounted to 840. To collect these he had to 

 perform the laborious task of reading 20,000 lines of concisely- written 

 Latin. The enumeration includes '-'not only the color-names used for 

 descriptive purposes by Fries himself, but also most of those used as 

 specific. And in making specific names there is a natural tendency to 

 use a color-name synonymous with another, simply from the fact of the 

 most obvious one having been already used. For instance, a describer 

 wishes to name a white species J.gancM§ albus; but when he finds that 

 name is preoccupied, he names his species Ag. candidus. Still we need 

 not conclude that he had the strict classical Latin differences of the two 

 words in his mind's eye ; he probably never thought that Ag. albus was 

 so named because it was of a dead white, nor in speaking of Ag. candidus 

 need he have meant to imply that jt was of a glistening white, as Cicero 

 might have done." 



Another difficulty that Mr. Wharton met with lies in the fact that 

 color-names were used in classical times with considerable indefiniteness. 

 Again, " much of the difficulty that surrounds the nomenclature of colors 

 is also due to there being no authoritative code. In each branch of art 

 or knowledge at the present day, different names are used for the same 

 colors. The ' purple ' of the cardinal is crimson ; the ' pink ' of the 

 huntsman is scarlet. An artist calls his colors by the names under 

 which he buys them," * * * ''consequently mycologists must
