258 SECTION HYGROPHORUS 



Observations — When fresh, this species resembles H. eburneus. 

 On drying, the pileus and lamellae of H. eburneus assume a buff to 

 yellow color, whereas in H. chrysaspis the lamellae become very dark 

 red-brown (near "blackish brown [1]"), and the pileus becomes "clav 

 color" to "tawny" or rusty brown, with dark to blackish disc. These 

 changes in color, according to Kiihner and Romagnesi ( 1953 ) , may take 

 place in one or two days if the carpophores are left in the laboratory. 

 They also state that J. Schaeffer recognizes H. chrysaspis with the aid 

 of KOH which immediately causes a brownish orange to chrome yellow 

 coloration, whereas KOH does not noticeably react on H. eburneus. 



Through the courtesy of Metrod and Josserand of France, and Bas 

 of the Netherlands, we have received specimens of H. chrysaspis. Our 

 collections agree well with the European material in both macroscopic 

 and microscopic details. 



It is interesting to note that the original description indicates that 

 the species occurs in conifer forests and that the carpophores are odor- 

 less and tasteless. Kiihner and Romagnesi ( 1953), on the contrary, state 

 "Odeur speciale, plutot desagreable," — "sous hetres." Our material, 

 mostly from under beeches, has no strongly distinctive odor. 



It is probable that Peck's H. laurae var. unicolor, which he re- 

 ported ( 1902c) from New York, is H. chrysaspis. Kauffman ( 1918) rec- 

 ognized Peck's variety, but he attached it to H. eburneus.
