Leucosporae 



This fungus is so inviting in quantity and beauty that one turns from cntocybe. 

 it with a regret that lingers. Eaten in quantity it acts upon some persons 

 as an emetic. I have several times eaten of it without other than 

 pleasurable sensations, but persons partaking of the same cooking have 

 been sickened. 



C. fumo'sa Pers. fumus, smoke. Pileus 1-3 in. across, fleshy, mar- 

 gin thin; convex, often gibbous when young, regular or wavy, even, 

 pellicle not separable, glabrous, sooty-brown, soon livid or gray when 

 dry. Gills adnate in regular forms, but often decurrent when the pileus 

 is irregular, crowded, distinct, grayish-white from the first. Stem 23 

 in. long, 3-6 lines thick, almost equal, often twisted or curved, gla- 

 brous, dingy-white, apex mealy, solid, fibrous. Spores subglobose, 

 5 6/u. diam. 



In woods. Autumn. 



Gregarious, somewhat cespitose, tough, rather cartilaginous. Pileus 

 truly obtuse, never streaked, often regular. Smell none. Fries. 



Var. po Hits. Densely and connately cespitose. Pileus convex, then 

 plane, obtuse, smooth, gray. Stem flexuous, smooth. Gills crowded, 

 whitish. Edible. Cooke, 1891. 



Var. polius found growing in large quantities in Boston navy yard in 

 stone barn. Determined by Professor Peck. A fair edible. R. K. 

 Macadam. 



This woods-growing Clitocybe has been many times found by me in 

 a hot-house in Haddonfield, N. J. Professor Peck confirmed my iden- 

 tification. Either its spores or mycelium had evidently been carried 

 thither in the wood-earth used by florists. The hot-house crops ap- 

 peared in March, and continued until June. 



Several of the plants showed an effort to comply with some condi- 

 tion unusual to them, by producing gills upon the upper side of the 

 pileus. Those below were venose and crisped. 



This wild species had thus been brought into cultivation. The culti- 

 vated plants were much more tender than the wild. Both are excellent. 



C. COnnex'a Pk. connexus, joined. From its relation to Tricholoma. 

 Pileus thin, convex or expanded, subumbonate, clothed with a minute 

 appressed silkiness, white, the margin sometimes faintly tinged with
