Agaricus (Lepiotd) naucinus, Fries, Epicr., p. 16; Cke., 

 lldbk., p. 15; Cke., Illustr., pi. 15. 



In fields, cucumber frames, &c. 



Somewhat caespitose. Eesembling L. excoriata in general 

 appearance, but differing in tlie superior, thin ring, &c. In 

 Cooke's figure the pileus is slightly depressed at the disc, 

 and no indication of an umbo. 



Lepiota cepaestipes. Sow. 



Pileus 1-3 in. across, flesh thin ; ovate then expanded, 

 disc fleshy and broadly umbonate, mealy and squamose with 

 evanescent plumose scales, pale sulphur-yellow or white, 

 disc often brownish, margin plicate ; gills free, at length 

 distant from the stem, 1-2 lines broad, rather distant, 

 whitish or wdth a yellow tinge ; stem 3-6 in. high, 1^ line 

 thick at the apex, swollen, often very considerable at the 

 middle or near the base, floccose, white or pale yellow^, 

 hollow ; ring distant ; spores elliptical, 7-8 X 4 /x. 



Agaricus cepaestipes, Sow^erby, Fungi, t. 2 ; Cke., Hdbk., 

 p. 15 ; Cke., Illustr., pi. 5, also pi. 942 (as Agaricus (Lepiota) 

 cepjaestipes, var. cretaceus, Bulliard). 



On tan in hothouses, melon beds, &c. 



Gregarious or tufted. Probably an introduced species. 



Gregarious or tufted. AVhole plant white, pale suljDhur- 

 colour or j'-ellow. Pileus 1-3 in. broad, ovate-conical when 

 young, then campanulate, and finally nearly or quite plane, 

 darker in the centre, and more or less covered wath small 

 scattered fibrous scales, the flesh thin, and vanishing entirely 

 towards the margin, which is plicate and semi-transparent ; 

 the substance is however tough, and bears folding betw^een 

 the fingers without laceration. Lamellae numerous, thin, in 

 no regular series, the extremities next the stipes broad and 

 rounded, and separated from it by a circular space. Stipes 

 3-6 in. high, straight or crooked, firm, even, smooth, narrow 

 at the top, but ventricose below, and then narrower again at 

 the very bottom, somewhat pruinose, the centre at first fitted 

 with delicate silk}" fibres, at length hollows x\nnuliis perfect, 

 erect, persistent. Sporidia white, copious, elliptical. 



In decay the pileus turns brownish, and, according to its 

 situation, either dries up, or becomes covered with little 

 globules of fluid, and gradually dissolves. (Grev.)
