PLUTEOLUS. 



Pileus slightly fleshy, viscid, conical or campanulate then 

 expanded, the margin at first straight, appressed to tic- si 'an. 

 Lamellae rounded free. Stem subcartilaginous, separate from the 

 hymenophore. 

 Pluteolus expansus Pk. 



Pilcus 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 taperi 

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

 yellow. 



Spores 11 to 12 x (> to 7.5 /a. Pileus 2.."> to 1 cm. broad; stem 

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

 ground. 



Var. 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 si raight 

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

 mostly fragile; when young or moist the pileus has a watery 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.."> cm. long, about 2 

 mm. thick. Spores ellipsoid, dark-ferruginous, 12 to 10 x 7..") 



to 10 (x. 



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

 weather the plants deliquesce like species of ( 'oprinus, the lamellae 

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

 globose, ellipsoid, or somewhat oblong, 10 to 12 x G to 7 p.., or 

 12 to 14 x S to 12V-
