REPORT ON EDIBLE FUNGI 1895-99 1 39 



tosu m, has the cap of a uniform sooty brown color. Saunders and Smith 

 figure a variety which occurs in England and which has the cap greenish 

 yellow with a sooty brown center almost exactly like our plant. The brown 

 color of the central part of the cap is very conspicuous and is suggestive of 

 the name we have given to this variety. 



Clitocybe clavipes (Pcrs.) Fr. 

 Club stemmed Clitocybe 



PLATE 46, Jig. 1-6 



Pileus broadly convex or nearly plane, very thick and fleshy, almost 

 obconic, soft, glabrous, brown or sooty brown ; lamellae subdistant, decur- 

 rent, white or barely tinged with yellow, stem tapering upward, solid, col- 

 ored like the pileus; spores .00025 to .0003 of an inch long, .00016 to .0002 

 broad. 



The club stemmed clitocybe may easily be recognized by its peculiar 

 shape and colors. The cap may be compared to a very broad and short 

 inverted cone and the stem to a very narrow elongated cone, the apices of 

 the two being united. Between the brown upper surface of the cap and the 

 similarly colored stem the white gills intervene as if to separate them. 



The upper surface of the cap is generally nearly flat and even, but 

 sometimes it may be a little depressed in the center, and sometimes it is 

 furnished with a small umbo. Its margin is at first involute, but spreading 

 when mature. It varies in color from grayish brown to a dark sooty brown, 

 with the center occasionally darker than the margin. The flesh is white 

 and in mature plants is rather soft. The flesh of the stem is also white and 

 somewhat soft and spongy, but elastic. The color may sometimes be a little 

 paler than though similar to that of the cap. In shape it is commonly 

 tapering from the base upward, but in some cases the base is more abruptly 

 enlarged, making it almost bulbous. Its surface may be adorned with a few 

 fibrils. 



The pileus is 1 to 3 inches broad ; the stem 1 to 2.5 inches long and 3 

 to 4 lines thick at the top, but much thicker at the base. The plants grow 

 in a scattered manner or rarely tufted, and are specially fond of pine woods. 

 They occur from August to October.
