REPORT OF THE STATE BOTANIST Kjll J^ 



ficial silky film, white when moist, shining white when dry ; lamellae 

 very thin, close, narrow, adnate becoming decurrent, white ; stem 

 even, equal, waxy, polished, hollow or nearly so, shining, often 

 curved, rooting and villose at the base ; spores 4-6 x 4 fi. 



Gregarious. Among fallen leaves in woods. Common, Sep- 

 tember and October. 



Said by Cooke to be farinaceous. By the character of the stem 

 approaching Omphalia. In its form related to the section Cyathi- 

 formis, but not truly hygrophanous. Small and somewhat tough. 



Clitocybe dealbata Sow. 



IVORY CLITOCYBE 



Sylloge V, p.I57 



Pileus slightly fleshy, convex becoming plane or with upturned 

 and sometimes wavy margin, dry, even, glabrous, subshining, tough, 

 white, taste mild ; lamellae close, thin, adnate, white ; stem fibrous, 

 equal stuffed, pruinose or mealy at the top, white ; spores ellipsoid, 

 4-5 x 2-2.5 M . 



Pileus 2.5-4 cm broad ; stem 2-3 cm long, 2-3 mm thick. 



Gregarious. Grassy places. Common. September and October. 



Var. minor Cke. differs in its smaller more regular form, 

 opaque pileus and agreeable farinaceous odor. 



Var. deform ata Pk. Pileus thin, very irregular, convex or 

 centrally depressed, wavy or lobed on the margin, snowy white, flesh 

 pure white, taste farinaceous ; lamellae close, adnate or slightly 

 decurrent, transversely venose, often anastomosing or connected by 

 veins, frequently eroded on the edge and sometimes transversely split, 

 whitish ; stem irregular, sometimes compressed, more or less con- 

 fluent at the base, stuffed or hollow, white, with a soft pure white 

 downy tomentum below ; spores subglobose, 3-4 /x long, nearly as 

 broad. 



On mushroom beds in a greenhouse. Wayne co. March. The 

 specimens grew in mushroom beds made in a poorly lighted apart- 

 ment, in which a temperature of 55°-6o° was maintained. These 

 conditions doubtless had some influence in causing the irregular, 

 tufted mode of growth. The pure whiteness, thin pileus and the 

 farinaceous taste and odor indicate a relationship with Clitocybe 

 dealbata Sow. so intimate that it is recorded as a variety of it. 

 That species is also sometimes found growing on mushroom beds.
