CLASSIFICATION OP AGARICS |2fi 



first, amber when mature, fading to brownish-graj uiili m chestnut 

 colored umbo; the gills were fuscous ;ii first, and the annulus lean 

 fully developed. Form (B) bad a waterj cinnamon-brown cap 

 when mature, fading to ochraceous-tan ; the ^i !ls were pallid, ochra- 

 crous ,it first, and the annulua more persistent. The pileus of both 

 had the characteristic villose covering, the same Bpores and babit. 

 The jjills of our specimens arc never truly crowded, and in thi^ re 

 sped differ from the European descriptions and from specimens 

 which I collected in Sweden. The microscopic structure of both 

 forms was alike. The upper surface of the fresh pileus is compo 

 of a differentiated layer of two kinds of cells, one forming erect, 

 fasciculate fibres alternating with n layer of larger cells; these 

 fasciculate tufts of narrow cells arise from separate poim-- in the 

 surface of the pileus and produce the villose effect. This upper 



layer is easily dissolved by rains and often disappears Leaving 

 the pileus glabrous. The stem is usually hollow, 1 m I it is not rare 

 to find a stalled or solid axis. Moth forms are caespitose. The 



variation in size is such, even in the same collect ions, that it i> 



very doubtful whether C. paleaceus should be kepi separate.

Differing from C. hemitrichus Fr. in more slender habit, longer 

 stem, the universal veil forming delicate, evanescent, subannular, 

 white fibrillose /.ones along tbfe stem, and in the pileus being more 

 acutely conical. The colors are fuscous, paler.
