t 

 Pileus 1 to 2.5 iu. broad; stem 1 to 1.5 iu. long, 3 to 5 lines thick. 

 Among mosses iu open places. Catskill mountains. September. 

 This and the next in-eceding species belong to the section Geuuiua. 



Tricliolonia putidum, Fr. 



Under pine troes. Catskill moiiutains. September. 



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

 except that the pileus is not umbonate; but this character is limited 

 by Fries in Icones Selectte to young plants. 



Clitocybe subsimilis, n. .sp. 



Pileus at first conical or subturbinate, then plane, nearly obconicah 

 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; lamella; 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, white; spores broadly elliptical or sub- 

 globose; .0002 to .00025 iu. long, .00016 to .0"002 broad. 



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



Under pine trees. Catskill mountains. September. 



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

 said to be a white variety. 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 abruptly bulbous. Its resemblance to C. claclpeit Ims 

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

 pileus and subdistant lamelLe. 



Variety mondrom. Lamelhu reticulately branched or anastomosing, 

 causing the hymenium to apj)ear porous either wholly or iu part. 



With the typical form. 



Clitocybe caespitosa, n. sp. 



Pileus thin, infundibuliform, often ii-regular, slightly silky, hygro- 

 phanous, grayish brown when moist, subcinereous or argillaceous 

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

 white; stem equal, stuffed or hollow, silky, white; spon-^ nunul... 

 subelliptical, .00012 to .00010 in. long. 



Pileus 1 to 1.5 in. broad; stem about 1 in. long, 2 to 3 linot, thiik. 



Thin woods! Catskill mountains. September. 



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

 irregular, deformed appearance. The pileus is somewhat porforutod. 

 The relationship is with C. expallens, V. Adii-oudackeusis. etc.
