LEUCOSPORI. 19 



In woods, chiefly among pine-leaves. Rare. Aug.-Oct. Lepiota. 



Smell like that of Lactarius theiogalus, approaching that of A. cristatus.

28. A. clypeolarius Bull. Typical form. Pileus 5-7.5 cent. 

 (2-3 in.) broad, beautiful tan-colour, slightly fleshy, at first acorn- 

 shaped, even, becoming tawny at the apex, wholly continuous, 

 though silky-soft, slightly crusted, with thick marginal down, 

 which then separates into a superior ring adhering to the stem ; 

 then campanulate and flattened, with a tawny umbo, otherwise 

 wholly broken up into floccose scales, very soft; flesh floccoso- 

 soft, 4 mm. (2 lin.) thick, white, watery when moist. Stem about 

 7.5 cent. (3 in.) long, 4-6 mm. (2-3 lin.) thick, stuffed with a dis- 

 tinct floccose-spider-web pith, soon hollow, equal or slightly 

 thickened at the base, soft, fragile ; at first continuously scaly- 

 squarrose from the yellowish veil being broken up into patches ; the 

 floccose scales easily separate, so that the stem is somewhat naked, 

 fibrillose, pallid, striate at the apex above the fugacious ring. 

 Gills free, approximate, 6 mm. (3 lin.) broad, soft, crowded, shin- 

 ing white or becoming yellow. 



Odour weak, often scarcely any. It is so very changeable, that it is scarcely 

 possible to include all its forms under a common description. The scales on 

 the pileus vary yellow, rufescent, ferruginous, and the gills white, yellowish. 

 In shady pine-woods a form occurs with white-floccose-woolly stem, pileus 

 wholly woolly with exception of the continuous disc, sometimes yellowish, 

 sometimes becoming pale. In marshy thickets there is a form with the squa- 

 mulose pileus rose-coloured. In very shady beech-wood, on rotten wet leaves, 

 a more slender form occurs, with a floccoso-squamulose stem, and white pileus 

 elegantly variegated with concentric fuscous scales. Var. pratensis Bull, is 

 floccose only below the fibrillose ring. There are many forms in hothouses 

 departing from the type, as Fl. Dan. t. 1732. 



In woods, shaded borders, and hothouses. Uncommon. Oct.- 

 Nov. 



Spores oblong, uniguttate, 16-20 x 5-6 mk. K.; 18-20x4-5 mk. B. Name 

 clypeus, a shield. Bull. t. 405, 506. f. 2. Fr. Monogr. i. p. 24. Hym. Eur.

29. A. metulsesporus B. & Br. Pileus 2.5 cent, (i in.) broad, 

 white, rather fleshy, campanulate, obtuse, sulcate, with small 

 pallid scales, margin appendiculate. Stem 5-12.5 cent. (2-5 in.) 

 long, 2 mm. (i lin.) thick, stuffed, somewhat equal or slightly 

 clavate, pallid, lemon-coloured within. Gills approximate, ven- 

 tricose, nearly 4 mm. (2 lin.) broad, white. 



In external characters it approaches A. clypeolarius, but it is at once dis- 

 tinguished by the length of its spores. Mycelium thread-like.
