old stumps ; some of the pilei are nearly eight inches in diameter ; 

 the species is unwholesome if not poisonous. 



Tricholoma^ with adnate or more commonly sinuate lamellae is 

 the only other member of this group with a fleshy stem, conse- 

 quently a considerable number of species are classed as edible. 

 Among them are : 



T. eqiiestre with a viscid yellow pileus two to four inches wide 

 and bright sulphur yellow lamellae ; it commonly grows in pine 

 groves. T. siilfurciun resembles this in color, but the pileus is 

 not viscid ; it is regarded as a suspicious species. 



T. fra?ts?m{fans\i2iS a viscid tawny red or reddish brown pileus 

 about the same size as the last ; the stem is two to four inches 

 long and hollow or stuffed. 



T. imbrication resembles the last in size and color, but is dis- 

 tinguished by its pileus not being viscid and by its solid stem ; the 

 pileus often appears scaly from the rupturing of the epidermis. 



T. personatum is often abundant. The whole mushroom, pileus, 

 lamellae and stem are usually a pale violet lilac color when young, 

 fading somewhat with age. 



Hiatida with a delicate plicate pileus is represented by a single 

 species in North Carolina ; most of the species are tropical in their 

 distribution. The two remaining genera with sinuate or adnate 

 lamellae are Myceiia'\2,x\A CoIIybia \; the former with the margin 

 of the pileus straight is reputed to contain edible species, 

 but none are of much prominence. The latter contains several 

 very common species, some of which are said to be injuri- 

 ous ; others are commonly regarded edible. Among the com- 

 monest species is C. vehitipes, readily recognized by grow 



*This genus is largely represented in this country by about fifty spe- 

 cies. Peck (Reg. Rep. 44: 3S-64) has given a valuable synopsis with 

 full descriptions of the forty- six species occurring in New York. 



f Mycena contains about fifty-two American species ; no full synopsis 

 has ever been attempted. Peck (Reg. Rep. 23 : 80-S4) describes twelve 

 of the species occurring in New York State, but many more have been 

 since reported. 



:|: Collybia contains fifty-four American species Morgan (Jour. Cin- 

 cinnati vSoc. Nat. Hist. 6 : 173-177) describes thirteen species occurring 

 in Ohio, and Peck (Reg. Rep. 49 : 32-55) desci-ibes thirty-four species 

 known from New York,
