603. A. alnicola Fr. Pileus 5-7.5 cent. (2-3 in.) broad, yel- 

 low, at length becoming ferruginous and sometimes green, fleshy, 

 convex then flattened, obtuse, slimy when moist, but not truly 

 viscous, at the first superficially fibrillose towards the margin: 

 flesh not very compact, of the same colour as the pileus. Stem 

 5-7.5 cent. (2-3 in.) and more long, 12 mm. (}4 in.) thick, stuffed 

 then hollow, attenuato-rooted, commonly curved-flexuous, fibril- 

 lose, at first yellow, then becoming ferruginous. Cortina manifest, 

 sometimes fibrillose, sometimes woven into an arachnoid web. 

 Gills somewhat adnate, broad, plane, at firs I dingy -pallid or 

 yellowish-pallid, at length together with the plentiful spores 

 ferruginous. 



The gills vary decurrent and rounded according to situation. Odour and 

 taste bitter. There are two forms : A. pileus irregular, fibrillose round the 

 margin ; gills at first dingy pallid. B. salicicola, pileus somewhat gibbous, 

 smooth, rarely at the first floccoso-scaly ; gills at first yellowish-pallid. In 

 natural affinity it seems, especially salicicola, nearest to Pholiota aurivellits. 



On old stumps. Rare. Sept. -Oct. 



Spores subellipsoid, 8x5 mk. K. Name alnus, alder ; colo, to inhabit.

604. A. flavidus Schseff. Pileus 2.5-12.5 cent. (1-5 in.) broad, 

 bright light yellow, fleshy, convex then expanded, obtuse, even, 

 smooth, moist but not viscous, for the most part regular ; flesh 

 white, then becoming light yellow. Stem commonly 7.5 cent. 

 (3 in.) long, 6-10 mm. (3-5 lin.) thick, stuffed then hollow, some- 

 times attenuated sometimes thickened downwards, somewhat 

 flexuous, fibrillose, light yellow, at length, especially at the base, 

 becoming ferruginous. Cortina manifest, woven, adhering to the 

 margin of the pileus, white, rarely almost in the form of a ring. 

 Gills adnate, not much crowded, at first whitish, then light yellow, 

 at length tawny-ferruginous. 



Spores plentiful. It can be safely distinguished from A. fascicularis and its 

 allies by its purely ferruginous spores. Forming large clusters, but very vari- 

 able in size, according as the weather is favourable to its growth.
