Mycologia 



cream color or pale-ochraceous when dry, either faintly striate 

 or sulcate-striate on the margin ; lamellae 1-2 lines wide, distant, 

 ventricose, adnate or slightly decurrent, tawny-ochraceous ; stem 

 slender, flexuous, often uneven, hollow, pruinose at the top, 

 downy at the base, pale-yellow or cream color; spores ellipsoid, 

 7-5 X SP" Pileus 4-8 lines broad ; stem 1-2 in. long, about i line 

 thick. 



Described from specimens collected by McClatchie among 

 mosses on gravelly hillsides near Pasadena, California. Types 

 not seen.

Pileus thin, convex, glabrous, ferruginous ; lamellae broad, ar- 

 cuate, distant, adnate or slightly decurrent, ferruginous; stem 

 short, slender, glabrous, hollow, brown; spores ellipsoid, uninu- 

 cleate, 10-12 /X long, 7-8 /X broad. Pileus 6-10 mm. broad; stem 

 6-14 mm. long, scarcely i mm. thick. 



Described from specimens collected on the ground at Port 

 Clarence, Alaska, Trelease 562, 567. The dried specimens are 

 said to resemble Omphalia Campanella in color, but the spores 

 are ferruginous, 10-12 X 7-8 /x.

Several divisions of this genus have been proposed but none of 

 them are satisfactory in the presence of the actual specimens. 

 The veil, the attachment of the gills, the habitat of the plant, the 

 shade of color in the spores, and the viscidity of the pileus may 

 all be helpful in the separation of species, but they do not seem to 

 furnish reliable and convenient characters for the segregation of 

 the genus. 



Most of the species here treated are plainly congeneric and 

 rather difficult to separate from the descriptions alone. G. dec- 

 oratus and G. viridans are imbricate-scaly ; G. echinulisporus has 

 noticeably roughened or echinulate spores; G. laeticolor is bright- 

 red in color; G. sitbflavidus and G. viridans become green-spotted 

 when handled; and G. carbonarius has peculiarly dark-colored 

 gills when the spores mature.
