54 AGARICINI. 



Hygrocybe. which when it breaks up become revolute), pale-white. Cortina 

 appearing only as a silky narrow white zone round the very mar- 

 gin of the pileus. Gills adnate, moderately crowded, 4-6 mm. 

 (2-3 lin.) broad, watery cinnamon, even at the sides. 



No trace of a fibrillose cortina has been observed in any stage of its growth. 

 In pine woods the stem is not bulbous, but attenuated downwards. 



In old pastures beside stumps. Dun, 1876. Scone, 1877.

Name — durus, hard ; acinus, berry. Hard. From the coating of the 

 pileus and stem. Fr. Monogr. ii. p. 96. Hym. Eur. p. 388. B. & Br. n.

110. C. dilutus Fr.— Pileus about 5 cent. (2 in.) broad, at first 

 bay-brown, even watery brick-colour, tan when dry, in either 

 state opaque, somewhat fleshy, convex then expanded, umbonate 

 (umbo thin, vanishing), smooth when the veil is rubbed off. 

 Stem 5-7.5 cent. (2-3 in.) long, 4-8 mm. (2-4 lin.) thick, stuffed 

 then hollow, slightly attenuated from the base, externally not 

 cartilaginous - polished, white - silky, then becoming smooth, 

 opaque, whitish. Gills deeply emarginate, very ventricose, 6-8 

 mm. (3-4 lin.) broad, crowded, pale cinnamon, not shining. 



Inodorous. Veil white, often collapsing into spots on the stem or forming 

 spurious zones, and on the pileus forming a white-silky zone round the mar- 

 gin. Wholly soft and fragile, and thus readily distinguished from the much 

 more robust C. arvieniacus with which it agrees in colours, so that it was 

 formerly taken for a thinner form of that species. 



In woods. Rare. 



Not recorded since the time of Bolton. Name — dilutus, diluted, watery.

111. C. saturninus Fr. — Pileus 5-7.5 cent. (2-3 in.) even 

 10-12.5 cent. (4-5 in.) broad, dark bay-brown somewhat umber 

 when damp, soon becoming pale, brick-colour, changing colour 

 very much, unequally fleshy, campanulate when young, then ex- 

 panded, obtuse, even, smooth (or when young superficially silky 

 round the margi?i with the veil) ; flesh violaceous then whitish, 

 thin at the circumference. Stem 5-7.5 cent. (2-3 in.) long, 1-2.5 

 cent. (>2-i in.) thick, occasionally shorter and bulboso-ventricose, 

 firm, stuffed, internally spongy, thickened downwards, fibrillose, 

 deep violet, but becoming white. Cortina inferior, abundant, 

 white. Gills rounded-adfixed, very broad (8 mm., 4 lin.), crowded,
