442. A. nidorosus Fr. Pileus as much as 7.5 cent. (3 in.) 

 broad, fawn-cinereous when fresh, livid when dry, somewhat 

 membranaceous (composed of two thin plates), convex then 

 expanded, and at length often concave and irregularly shaped, 

 rimose, very fragile, wholly smooth, but silky shining when dry. 

 Stem 5-7.5 cent. (2-3 in.) long, 2-4 mm. (1-2 lin.) thick, stuffed, 

 almost solid, wholly equal, smooth, even, becoming pale-white, 

 white-pruinose at the apex. Gills emarginato-free, broad (6 mm., 

 3 lin., and more), at length distant, fragile, pallid then flesh- 

 colour, sometimes undulato-flexuous. 



Fragile, with a strong alkaline smell, but it also occurs inodorous. Much 

 thinner than A. rhodopolius, which is somewhat like it.

 soon flattened and depressed, but the disc is also obtusely and 

 obsoletely umbonate, even, very smooth, margin thin, bent in- 

 wards, flexuous, pellucid-striate. Stem 5-7.5 cent. (2-3 in.) long, 

 about 4 mm. (2 lin.) thick, fistulose, smooth, round when young, 

 then compressed, shining. Gills slightly adnexed, broadly 

 emarginate near the stem, 6-8 mm. (3-4 lin.) broad, very ventri- 

 cose, flaccid, the shorter ones narrower, white then flesh-colour, 

 the edge, which is quite entire, becoming fuscous. 



Very fragile, inodorous, becoming wholly pale-white. Primary form some-
