REPORT OF THE STATE BOTANIST I9OO 163 



Clitocybe nebular is {Batsch) Fr. 



Woods. Westport. October. In young specimens the stem is ap- 

 parently solid. The species is quite rare with us and appears late in the 

 season. 



Clitocybe albissima Pk, 



This beautiful species was quite plentiful in the woods about Flood- 

 wood in August and September. It grows in groups and is snowy 

 white from its first appearance to full maturity. It is thought by some 

 to be the same as the European C. cerussata, with the description 

 of which it agrees very closely, but that species is described as having 

 the pileus moist. I have never seen this character exhibited by our 

 plant. It has a dry appearance even after rain, and, when the inner 

 substance shows moisture, the surface of the pileus appears just as white 

 and dry as ever. In old plants the pileus sometimes becomes cir- 

 cinately or areolately rimose, -and sometimes the stem is partly hollow. 

 The cavity may be near the top or near the bottom of the stem. 



Clitocybe adirondackensis Fk. 



This species is common in the Adirondack Avoods in September. 

 There are two forms, one of which has the pileus and stem white or 

 whitish, the other very pale tan color. The latter should be carefully 

 separated from C. infundibuliformis membranacea Fr. 



Clitocybe patuloides Pk. 



PLATE E, FIG. 1-7 



This species was described in '^2d report of the N. Y. state mus. p. 25, 

 from specimens collected at Brewerton in 1878. It was found again near 

 AVestport in October 1900. As tlie recent specimens indicate a some- 

 what wider range of variability in its characters than the Brewerton 

 specimens, it has seemed best to give a new and more full description of 

 the species and illustrate it by a figure, specially since it is closely allied 

 to Tricholoma patulum Fr., even though this species is placed 

 in another genus. 



Pileus fleshy, firm, rather thick, convex, becoming nearly plane or 

 somewhat centrally depressed, glabrous, even and white when young, 

 with the margin incurved, becoming pale ochraceous with age and often 

 squamose or rimosely areolate, flesh white, taste mild, odor like that of 

 mushrooms; lamellae thin, close, slightly or strongly decurrent, forked or 

 anastomosing at the base, white ; stem usually short, equal or slightly
