 cylindrical or compressed, equal or tapering upwards, smooth, 

 solid, 2-5 mm. thick, apex blunt or pointed. Stem fairly 

 distinct, paler, sometimes yellowish. Flesh whitish, deep rose 

 beneath the hymenium. Internal structure of frequently 

 septate, irregular hyphae, 7-12 fx in diameter, semi-parenchy- 

 matous in transverse section; crystals sometimes present. 

 Basidia conspicuous, 35-40 x 7-10/x, granular or guttulate, 

 sterigmata 4, erect. Spores copious, smooth, hyaline, ovoid 

 or broadly elliptical, 7-10 x 5-6/x. 



Habitat. Amongst grass, moss, etc. Rare. Specimens from 

 near Hebden Bridge (C. Crossland, 1895-97) ; Morpeth (C. H. 

 Spencer Perceval, 1908, 1909, 1910); Halifax (C. Crossland,

 long, 3-5 /x in diameter, or 7-9 /x towards the centre of the club, 

 pseudoparenchymatous in transverse section. Basidia small 

 25-30 X 7-8 /x, guttulate; sterigmata 4, erect. Spores hyaline, 

 smooth, oval, 7-8 x 4-5 /i, contents granular.
