176. A. tuba Fr. Wholly white. Pileus 5-7.5 cent. (2-3 in.) 

 broad, fleshy, thin, convexo-plane, umbilicate, even, always with- 

 out stria at the margin, dead white when moist, shining whitish 

 when dry (somewhat hygrophanous), properly smooth, but at the 

 first sprinkled with a very thin, slightly silky, easily separating 

 film. Stem 5 cent. (2 in.) long, 4-6 mm. (2-3 lin.) thick, stuffed 

 then hollow, at length compressed, very tough, equal, naked up- 

 wards, not pruinate. Gills deeply and truly decurrent, horizontal, 

 very crowded, 6 mm. (3 lin.) broad, white becoming pale. 



" Gregarious, inodorous. Allied to Cyathiformes from the somewhat hygro- 

 phanous pileus. Nearest to A. pithyophilus, but easily distinguished by the 

 form of the pileus (umbilicate) and by the gills being deeply and attenuato- 

 decurrent. 



On dead leaves, &c. Coed Coch, 1878, c. Autumn. 



Name tuba, a trumpet. From its shape. Fr. Monogr. \. p. 127. Hym. 

 Eur. p. 99. Icon. t. 51. f. 2. B. & Br. n. 1736. C. Illust. PI. 112. Paul, 

 t. 65. f. 2-5 (base naked, but also and commonly villous). 



177. A. ericetomm Bull. Pileus 2.5-5 cent. (1-2 in.) broad, 

 white, fleshy, globose then plane or concave, somewhat turbinate, 

 obtuse, often excentric and when irregular somewhat repand, 

 smooth, shining. Stem scarcely 2.5 cent, (i in.) long, 4-6 mm. 

 (2-3 lin.) thick, solid, but floccoso-soft internally, evidently atten- 

 uated downwards, sometimes compressed, tough, naked, smooth, 

 white. Gills rather shortly decurrent, 2-4 mm. (1-2 lin.) broad, 

 somewhat distant, connected by veins at the base, persistently 

 white. 



So like Hygrophorus niveus that it is difficult to distinguish between the figures 

 of the two species, but the structure is very different ; for A. ericetorum is arid, 

 soft, elastic, with a pleasant odour in short nearest to A. infundibuliformis. 



Among short grass. Coed Coch, 1872, c. Sept.-Nov.
