Pileus 1 to 2.5 in. broad; stem 1 to 4.5 in. long, 3 to 5 lines thick. 

 Among mosse.s in open places. Catskill mountains. September. 

 This and the next preceding species belong to the section Genuina. 



Tricholoma putidum, Fr. 



Under pine trees. Catskill mountains. September. 



Our specimens agree accurately with the description of T. putidum^ 

 except that the pileus is' not umbouate; but this character is limited 

 by Fries in Icones Selectee to young plants. 



Clitocybe subsimilis, n. sp. 



Pileus at first conical or subturbinate, then plane, nearly obconical' 

 soft, fleshy, pure white, the margin at first involute and somewhat 

 tomentose, then even or marked with irregular ridges, as if from 

 matted tomentum, flesh white, taste mild; lamellae in the young plant 

 adnate, in the adult, decurrent, subdistant, often branched, white, the 

 interspaces venose; stem equal or merely subbulbous, by no means 

 obclavate, solid, soft, elastic, wliite ; spores broadly elliptical or. sub- 

 globose; .0002 to .00025 in. long, .00016 to .0002 broad. 



Pileus 1 to 1.5 in. broad; stem 1 to 2 in. long, 2 to 4 lines thick. 



Under pine trees. Catskill mountains. September. 



This species is closely related to Clitocybe clavipes, of which there is 

 said to be a white vax'iety. I have separated our plant not only 

 because of its pure white color, but also because of its peculiar stem, 

 which is not at all obclavate as in G. clavipes, though sometimes it is 

 slightly and abriiptly bulbous. Its resemblance to C. clavipes has 

 suggested the specific name. It is very unlike C. obtexta in its dry 

 pileus and subdistant lamelkB. 



Variety monstrom. Lamelhe reticulately branched or anastomosing, 

 causing the hymenium to appear porous either wholly or in part. 



With the typical form. 



Clitocybe csespitosa, n. sp. 



Pileus thin, infundil) aliform, often irregular, slightly silky, hygro- 

 phanous, grayish brown when moist, subcinereous or argillaceous 

 when dry; lamelhc narrow, close, decurrent, somewhat branched, 

 white; stem equal, stuffed or hollow, silky, wliite; sjDores minute, 

 subelliptical, .00012 to .00016 in. long. 



Pileus 1 to 1.5 in. broad; stem about 1 in. long, 2 to 3 lines thick. 



Thin woods. Catskill mountains. Sei^tember. 



The plant is remarkable for its csespitose mode of growth and its 

 irregular, deformed appearance. The pileus is somewhat perforated. 

 The relationship is with C. expallens, C. Adirondackensis, etc.
