CLASSIFICATION OF \«: ! RH 71.-, 



Clitocybe l'i. 

 (FronJ ilit- (Jreek, clitos, sloping, and cybe, head.) 



White-sporecl ; stein spongy-fleshy to fibrous, elastic, its flb< 

 continuous with the trama of pileus, hence ool separable. <iills 

 decurreni or acutely adnate, often separable from the | >i l«-n <. n>,t 

 emarginatc nor sinuate, margin of pileus a1 firsl involute. So 

 annulus. 



Fleshy, firm < »r sofl mushrooms, growing aiostly on the ground 

 or decaying leaves, sometimes on wood, in fields, road-sides or for- 

 est. Mostly medium to large size. 



The PILEUS is mostly glabrous or silky fibrillose, Bcaly in ;i few 

 species, sometimes with rather thick flesh, often quite thin and 

 flexible. Many are hygrophanous and change color during dry 

 weather and have scissile thin flesh, others are merely moist and 

 have thidker unchanging flesh. The surface is aever viscid. The 

 shape of tin* pileus varies greatly, convex to plane, obtuse, de- 

 pressed in the center, ambilicate or inf undibulif orm ; very regular, 

 irregular or compressed when clustered, or often merely wavy in 

 outline. The color of the pileus is generally white to tan, gray, 

 •lull reddish or brownish, although ;i U>w bright-colored species like 

 c. illudens and C. anisearia are quite common. The STEM lacks 

 the true cartilaginous rind of the genus Collybia; its outer layer 

 being fibrous or sometimes sofl fleshy, (though it may become hard 

 and cartilaginous-like in dry weather). Within it may l"- fibrous 

 throughout, i. e., Bolid, or spongy-stuffed and becoming more or 

 less hollow. The fibrous structure is length-wise and is continued 

 into the trama of the pileus and i;i\i-> the stem considerable elastic- 

 ity. The color of the stem is usually like that of the pileus. 

 The GILLS are mostly white, Bome are ashj brown, or become 

 ashy-colored in age; in tin- subgenus Laccaria, they are colored 

 reddish, violel or yellow. They are always attached to the stem, 

 sometimes deeply decurrent, sometimes adnate .it flrel and later 

 pseudo-decurrenl when the expanding pileus is elevated anteriorly; 

 whatever the mode of attachment, the gills, are narrowed t>> .1 point 

 where they terminate on the stem, in one ^\»'< ' ■'</. the 



gills are aberrant, being emarginate-adnate .1^ in Tricholoma. The 

 i:ills. when decurrent, are often unequally s.». some extending farther 

 down the stem than others, especially when tin- pileus is irregular. 

 In many species the -jills are of differenl texture from the trama of 

 the pileus and <;in be peeled of! from it. in this character approach*
