Leucosporae 



Olitocybe Adirondackensis Pk. Adirondack Clitocybe. Pileus cutocybe. 

 thin, convex or nearly plane and umbilicate, or centrally depressed and 

 funnel-form, glabrous, moist, white or pale tan color. Flesh white. 

 Lamellae thin, narrow, close, very decurrent, white. Stem nearly 

 equal, glabrous, stuffed or hollow, colored like the pileus. Spores sub- 

 globose or broadly elliptic, 4-5^ long, 3-4/x. broad. 



The Adirondack clitocybe is common in the northern forests of the 

 state, but is not limited to them. Its cap is thin, and soon becomes 

 nearly flat with a decurved margin and a central depression or umbili- 

 cus, or very concave by the elevation of the margin, and then it resem- 

 bles a wineglass in shape. Its margin is sometimes wavy or irregular. 

 In color it varies from white to a very pale red or tan color. White 

 specimens sometimes have the center slightly darker than the rest. 



The gills are very narrow, being scarcely broader than the thickness 

 of the flesh of the cap. They are closely placed, white and decurrent. 



The stem is nearly cylindric, smooth and stuffed or hollow. It is col- 

 ored like the cap. Often there is a white tomentum or cottony sub- 

 stance at its base. 



The cap varies in size and is 12 inches broad ; the stem 1.53 inches 

 long and 12 lines thick. It may be found from July to October. Its 

 flavor is suggestive of that of the common mushroom. Peck, 54th

Clitocybe macillosa Pk. Spotted Clitocybe. Pileus fleshy, con- 

 vex, often centrally depressed, glabrous, centrally marked with numer- 

 ous small round spots, yellowish-white, the young margin involute and 

 minutely downy. Flesh white, taste mild. Lamellae narrow, close, 

 very decurrent, whitish or slightly yellowish, some of them forked. 

 Stem equal or slightly tapering upward, glabrous or sparingly fibrillose, 

 stuffed, sometimes becoming hollow, whitish. Spores subglobose or 

 orbicular, 45^ broad. 



The peculiar mark by which the spotted clitocybe may be distin- 

 guished consists in the small round definite spots in the central part of 

 the cap. They have a slightly darker or watery or yellowish color and 

 appear as if depressed below the rest of the surface. The cap is smooth 

 and whitish or yellowish white and is generally depressed in the center 

 and decurved on the margin. The margin is usually adorned with, 

 slight, short radiating ridges. The flesh is white and the taste mild.
