somewhat cartilaginous, internally spongy, hence elastic, wholly Bygrocybe. 

 white. Cortina simple, white, somewhat sheathing, collapsing 

 and commonly leaving an adpressed (not annular) zone on the 

 stem. Gills adnate, at length slightly rounded, always crowded, 

 rather broad, at first pallidly then tawny cinnamon, shining. 



Handsomest in pine woods. Firm, bright, changeable. Pileus soon 

 destitute of white fibrils. There is a remarkable variety {falsarius) in which 

 the pileus is paler, light yellowish, white when dry. On heaped rotting leaves 

 in moist places the stem becomes very much swollen, among damp mosses it 

 is longer and more slender.

108. C. privignus Fr.— Pileus about 5 cent. (2 in.) broad, the 

 ground colour fuscous, but becoming hoary-pale with a very thin 

 white film, pallid-tan when dry, slightly and unequally fleshy, 

 convex then flattened (even reflexed and undulated), obtusely 

 umbonate, without striae, dry, but remarkably hygrophanous ; 

 flesh hygrophanous. Stem about 7.5 cent. (3 in.) long, 6 mm. 

 (3 lin.) thick, stuffed then hollow, sometimes attenuated from the 

 base, sometimes equal, most frequently twisted, silvery-pale, here 

 and there white-silky with the veil. Gills adnate, broad, not 

 crowded, distinct, at first watery, then opaque cinnamon, serrated 

 and white-fimbriate at the edge when perfect. 



Very fragile, strong smelling, but scarcely acrid. The most remarkable of 

 the group.

Spores pruniform, punctate, 8 mk. Q. Name—privigmis, a step-son. Re- 

 lation not apparent, but the plant being fragile occupies a singular position in 

 the group. Fr. Monogr. ii. p. 95. Hym. Eur. p. 388. Grevillea, vol. xiv.

109. C. duracinus Fr. — Pileus 5 cent. (2 in.) and more broad, 

 when moist watery brick-colour, tan when dry, always opaque, 

 fleshy, plane with a broad obtuse umbo, and with a singular 

 elevated ridge round the margin caused by the margin being 

 at first sharply and regularly bent inwards to the breadth of half 

 a line, at which stage it is clothed with white silkiness, and 

 afterwards becoming flattened, when it is naked and even ; 

 cuticle hard, rigid, fragile. Stem 7.5 cent. (3 in.) long, 12 mm. 

 {% in.) thick, solid, hard, somewhat bulbous but rooted at the 

 attenuated stem-like base, externally even, smooth, and rigid, with 

 a thick cartilaginous rigid separable cuticle (the fragments of
