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

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

 out stri^ at the rpargin, dead white when moist, shining whitish 

 when dry (somew^hat 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 deciir7'ent, horizontal, 

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



■ Gregarious, inodorous. Allied to Cyathiforvics from the somewhat hygro- 

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

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

 decurrent.

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

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

 obtuse, often excentric and when irregular somewhat repand, 

 smooth, shini?ig. 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 sho7'tly 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. ericetortim is arid, 

 soft, elastic, with a pleasant odozir — in short nearest to A. ij^fundibuliformis.
