A well-marked plant, often of large size and distinguished by tie- 

 white universal veil which forms a very thin sheath on the stem. 

 by the prevailing silky-tomentulose pileus and rather broad gills. 

 It was referred by Peck to the subgenus Telamonia, but the flesh 

 is scarcely hygrophanous, and the pileus ao1 glabrescent. The 

 gills are rarely '"rich sulphur-yellow" as described by Peck, 

 but the spores of the type-specimens are described above and 

 are quite distinct. Tt differs from C. annulatus and C. croceocolor 

 in the pale, delicate yellowish-white colors of cap ami stem. It is 

 apparently a native American species, r. newfieldiensis Ellis
