Agaricacese 



ciitocybe. distinct, livid then yellowish-white, smell weak, not unpleasant. () 

 Entirely watery white; stem hollow, somewhat striate, base glabrous; 

 pileus infundibuliform, margin deflexed, milky-white when dry. Gills 

 less crowded, but rather broader, whitish. Fries. 



Spores 3/A W.G.S.; 4-5x3-4^ Massee. 



Edible. Cooke. 



C. morbi'fera Pk. morbus, disease ; fero, to bear. Pileus thin, frag- 

 ile, glabrous, convex, becoming plane or centrally depressed, slightly 

 hygrophanous, grayish-brown when moist, whitish or cinereous when 

 dry, sometimes slightly umbonate. Gills narrow, close, adnate or 

 slightly decurrent, whitish or pallid. Stem short, equal, hollow, col- 

 ored like the pileus or a little paler. Spores minute, broadly elliptical, 

 4/x long, almost as broad. 



Pileus .5-1.5 in. broad. Stem about I in. long, ^-\ in. thick. 



Grassy ground and lawns. November. Washington, D. C. F. J. 

 Braendle. 



The species seems related to C. expallens, but the margin of the 

 pileus is not striate as in that fungus. The taste is very disagreeable 

 and remains in the mouth a long time. Two persons were made ill by 

 eating it, but their sickness lasted only about three hours. Peck. 



I have not seen this species. Its reputation is bad. Caution should 

 be observed. 



V. VERSIFOR'MES. 

 ** Pileus bright, of one color. 



C. trullisa'ta Ellis. Pileus fleshy, plano-convex, at length depressed 

 in the center, innate fibrous-scaly, becoming smoother on the disk, mar- 

 gin thin. Gills unequal, not crowded, coarse and thick, adnate with a 

 decurrent tooth, at length white pulverulent, purple-violet at first, be- 

 coming dark brick-red. Stem stuffed, fibrillose, with a long club- 

 shaped base penetrating deeply into the sand. Spores large, cylindric- 

 oblong, I5-2O/A. 



In old sandy fields. September to October. 



The interior of the stem in the young plant is like the gills, violet- 

 purple, and the club-shaped base is covered with a tomentose coat, to 

 which the sand adheres tenaciously.
