PLUTEOLUS. 



Pileus slightly fleshy, viscid, conical or campanulate then 

 expanded, the margin at first straight, appressecl to tho stem. 

 Lamellae rounded free. Stem subcartilaginous, separate from the 

 hymenophore. 

 Pluteolus expansus Pk. 



Pileus submembranaceous, becoming nearly plane or centrally 

 depressed, viscid, plicate-striate on the margin, brownish-och- 

 raceous, often tinged with yellow, gray, pink or greenish hues. 



Lamellae narrow, close, rounded behind, slightly adnexed 

 pale-cinnamon or ferruginous. 



Stem rather long, slender, fragile, equal or slightly tapering 

 upward, hollow, faintly striate, pruinose, yellow or greenish- 

 yellow. 



Spores 11 to 12 x 6 to 7.5 /*. Pileus 2.5 to 4 cm. broad; stem 

 7.5 to 10 cm. long, 2 to 4 mm. thick. Decaying wood and rich 

 ground. 



Yar. terrestris Pk. Pileus grayish-yellow, tinged with green; 

 stem greenish-yellow. Growing on rich or well manured soil. 



In manured lawn. Wheaton. July. The pileus in the 

 young plants is ovate-campanulate, viscid, dark-gray, becoming 

 dry and changing to a pale greenish-lemon color. Lamellae pale- 

 yellow, becoming ferruginous. Stem pale-yellow, its flesh con- 

 colorous, whitish below, becoming fibrillose toward the base as 

 the plants mature. Spores pale-ferruginous, agreeing with the 

 measurements given above. 



GALERA. 



Veil none or fibrillose; stem subcartilaginous, continuous with 

 the hymenophore, tubular; pileus more or less membranous, 

 conical or oval, then expanded, striate, the margin at first straight 

 and adpressed to the stem; lamellae not decurrent. Plants small, 

 mostly fragile; when young or moist the pileus has a wateiy or 

 hygrophanous appearance. Spores ferruginous. 

 Galera tenera Schaeff. 



Pileus thin, hygrophanous, somewhat membranous, conic- 

 campanulate, pale ferruginous and slightly striate when moist, 

 wholly even and whitish or creamy-yellow when dry, opaque. 



Lamellae adnate, ascending, rather close, linear, cinnamon. 



Stem straight, slender, fragile, hollow, somewhat shining, 

 striate upwards, colored like the pileus. 



Pileus 8 to 20 mm. broad; stem 4 to 7.5 cm. long, about 2 

 mm. thick. Spores ellipsoid, dark-ferruginous, 12 to 16 x 7.5 

 to 10 fji. 



In lawns, grassy places in fields and woods, etc. In moist 

 weather the plants deliquesce like species of Coprinus, the lamellae 

 dissolving into a yellowish mass. The spores are variable, sub- 

 globose, ellipsoid, or somewhat oblong, 10 to 12 x 6 to 7 /tx., or 

 12- to 14 x 8 to 12 p.
