shining, two-coloured ; root liairy, bulbous ; gills attenuated, 

 nearly free, ventrieose, white. — Bolt. t. 137. 



Amongst moss, about the roots of trees. Not common. 



138. A. (Mycena) dissiliens, Fr.; very brittle; pileussub- 

 membranaceous, conico-eampaiiulate, obtuse, lineato-plicate 

 halfway up ; stem attenuated, somewhat incurved, finely stri- 

 ate, cinereous, dark, strigose at the base; gills rounded, se- 

 ceding, at length free, broad, soft, dirty-white, grey at the 

 base.— So/^. t. 151.. 



On trunks of trees. About Halifax. The species takes its 

 name from the stem, when compressed, breaking up into re- 

 volute laciuipe. Strong-scented. 



139. A. (Mycena) alcalinus, Fr.; rigid, but brittle, strong- 

 scented; pileus submembranaceous, bell- shaped, obtuse, na- 

 ked, deeply striate, moist, shining when dry ; stem smooth, 

 slightly sticky, shining, villous at the base ; gills adnate, rather 

 distinct, white, at length tinged with blue. 



On trunks of trees. Common. Easily distinguished by its 

 strong nitrous scent, like that of fermented walnuts. Often 

 tinged everywhere with yellow or pink. Solitary or csespitose. 



140. A. (Mycena) pauperculuSj, 5erA:.; strong-scented; pi- 

 leus obtusely conical or hemispherical, minutely innato-fibril- 

 lose, subniembranaceous ; stem smooth, rooting, villous at the 

 base; gills at first free, then adnexed, white. 



Inside of decayed stumps. Not common. Minute, ochra- 

 ceoiis-white, at length stained from the wood. Odour fari- 

 naceous. Gills adnexed, from the growth of the pileus, which 

 is sometimes striate from translucenec. This, perhaps, would 

 be better placed before No. 137.

 branaceous, l)ell-shaped, convex, obtuse, lineato-striatc ; mar- 

 gin crenate, appcndiculatc ; stem straight, pellucid, membra-
