2 6 AGARICUS. 



Lepiota. the pileus. Ring continuous with the cuticle of the pileus and 

 stem, at first entire, spreading. Gills free, crowded, ventricose, 

 white. 



On the ground in woods. Hereford, &c. Autumn. 



The English plant agrees in everything with that of Bulliard, except in the 

 less persistent ring, which, however, is sometimes attached to the stem, some- 

 times to the edge of the pileus. B. ^ Br. Name — ju-eVo?, middle, fj^op(j>ri, form.

B. CUTICLE OF PILEUS VISCOUS, CONTINUOUS. 



46. A. medullatus Fr. — Pileus 4-6 cent. {i%-2% in.) broad, 

 white, varying with the disc grey, slightly fleshy, convexo-plane, 

 umbonate, even, smooth, viscous, soft ; flesh soft, watery. Stem 

 about 7.5 cent. (3 in.) long, 6 mm. (3 lin.) thick, hollow, the thick 

 exterior coat easily separable from the interior, distinct, firm, at 

 length fistulose tube, equal, fragile, dry, silky and squamulose 

 below the veil, striate at the apex. Ring iiiconiplete, becoming 

 torn, commonly appoidiculate at the margin of the pileus which 

 hence appears as if looihtd-jijfibriate, scarcely prominent on the 

 stem. Gills quite free, broader in front, ventricose, crowded, plane, 

 shining white. 



Odour of radish. Flesh almost that oi A. clypeolarius.

Easily distinguished by the internal separable tube of the stem. Name — 

 medulla, pith. From the pith-like centre of the stem. Fr. Motiogr. i. /. 32.

47. A. gloiodermus Fr.— Pileus 4 cent, (i^ in.) broad, or 

 little more, brownish-red, slightly fleshy, ctnnpaiiulate then con- 

 vex, obtuse or broadly gibbous, even, smooth, smeared with thin 

 ghite?ij flesh soft, white. Stem about 7.5 cent. (3 in.) long, 4-6 

 mm. (2-3 lin.) thick, stuffed with spider-web threads, equal, dry, 

 soft, whitish, externally Jloccoso- scaly as far as the incomplete 

 torfi ring, naked, however, above it, whitish or rufescent. Gills 

 free, approximate, ventricose, broad, crowded, shining white, not 

 spotted. 



Like^. delicatus it holds a middle place between mesomorphi and the typical 

 species of this division {B), for the pileus is viscous, but the stem dry and 

 clothed with flocci. It resembles A. clypeolarius, but the pileus is always con- 

 tinuous, smooth, viscous.
