30. L. cyathula Fr. — Pileus 2.5-5 cent - ( I_2 in.) broad, slightly 

 fleshy, convexo-plane, umbonate, at length pla?io-depressed, umbo 

 often vanishing, viscid in wet weather, soon dry, always very 

 opaque, when in full vigour even, rufescent-brick or flesh colour, 

 somewhat zoned, when dry beconii?ig pale, livid or flesh-clay- 

 colour, hoary -tan, rimoso -rivulosej flesh white - flesh- colour. 

 Stem about 5 cent. (2 in.) long, 2-10 mm. (1-5 lin.) thick, stuffed, 

 internally spongy-soft, equal, round, even, smooth, pale, at length 

 whitish. Gills decurrent, very crowded, thin, scarcely reaching 

 2 mm. (1 lin.) in breadth, linear, white-flesh-colour then yellowish. 

 Milk white, imchangeable, acrid. 



Growing in troops, for the most part very thin and very small, but larger, 

 firmer, and darker specimens occur. Allied to L. vietus, but remarkable for 

 its stature, thinness, and mode of growth ; easily distinguished by the white 

 milk being u?icha?igeable whc?i the gills are -wounded, by its having at the 

 first scarcely any odour, but a strong smell of bugs when withering or half- 

 dried. It varies with the pileus zoneless, not umbonate. 



In woods. Rare. Aboyne, &c. Aug.-Nov.

** Pileus unpolished, squaviulose, &c. 



31. L. mfus Fr. — Pileus 7.5-10 cent. (3-4 in.) broad, bay- 

 brown-rufous, fleshy, umbo7iate when young, soon depressed with 

 an umbo, and at length infundibuliform, wholly zoneless, dry, 

 at the first flocculoso-silky, but soon polished, smooth, somewhat 

 shining, margin involute when young, somewhat whitish-to7ne?i- 

 tosej flesh not compact, pallid. Stem 5-7.5 cent. (2-3 in.) long, 

 about 12 mm. {%, in.) thick, stuffed, somewhat fragile, equal, 

 obsoletely pminate or wholly smooth, rufescent, but paler than the 

 pileus, white- pubescent at the base. Gills adnato- decurrent, 

 crowded, about 3 mm. {1% lin.) broad, quaternate, scarcely- 

 branched, ochraceous or pallid then rufescent. Milk white, 

 unchangeable. 



Odour none. Taste very acrid, stinging. The colour of the pileus when 

 older or dried passes into cinnamon-rufous. There is a smaller var. which 

 must be carefully distinguished from L. subdulcis ; very bitter. 



In pine woods. Common. June-Nov. 



The umbo is remarkably persistent and distinct even when ?nost deeply 

 infu?idibuliform. Very poisonous. Spores globose, white. Fr. ; subsphaeroid, 

 8 mk. K. ; scarcely echinulate, almost round, 5 mk. W.G.S. Name — rufus,
