Amongst grass in rich pastures. King's ClifFe, Oct. 2, 1860. 



Pileus about half an inch across, ovate, obtuse, dark brown, 

 turning pale, sprinkled with little fibrils more than half-way up, 

 not striate ; stem nearly straight, 2 inches high, 1^ line thick, 

 fibrilloso-silky, rather strong, white with a pale under-tinge of 

 brown, fistulose, the walls within white with down ; gills ascend- 

 ing, bfoad behind, adnatc, umber-brown, tinged with the dark 

 spores. 



Allied to A. noU-tangere, hut distinct in character from all the 

 neighbouring species.

921. A. (I'sr-Miyra) mastiger, n. sp. Pileo conico-campanulato 

 repando e spadiceo alutaceo; stipite stricto sursum attenuate ; 

 lamellis adscendentibus affixis umbrinis. 



On the roadside amongst grass. Apethorpe, Sept. 20, 1860. 



Pileus about an inch across, at first nearly cylindrical, obtuse, 

 then conico-campanulatc, with a strong mammiform umbo, 

 repand, dark rich brown when moist, umber- tan when dry, 

 somewhat fleshy, not striate ; margin straight ; stem 3 inches or 

 more high, 1^-2 lines thick, attenuated upwards, white, smooth 

 or fibrillose and furfuraceous, fistulose, pale uraber within, and 

 as the plant dries acquiring the tint of the pileus, but pale ; 

 veil none; gills umber, paler on the edge, rather narrow, affixed, 

 ascending. 



This fine species is allied to A. conopilus, but differs in many 

 respects. The dark colour and mammiform apex are very 

 striking.

922. A. (Psathyra) Gordoni, n. sp. Csespitosus ; pileo cam- 

 panulato pallide cinereo demum albescente plus minus floccoso- 

 squamuloso sulcato-striato ; stipite flexuoso floccoso glabrescente 

 sursum albo pruinoso ; lamellis adscendentibus anguste adnatis 

 distantibus cinereis. 



On old stumps. Overton Longueville, Oct. 10, 1860. The 

 Marchioness of Huntley. 



Densely csespitose. Pileus H inch across, campanulate, mem- 

 branaceous, at first pale cinereous, then white, sprinkled with 

 white floccose scales, sulcato-striate ; stem 2 inches high. Inline 

 thick, transversely undulated, pruinose above, floccose below, 

 but becoming at length smooth and shining, brittle, fistulose; 

 gills ascending, narrowly adnate, distant, moderately broad, 

 scarcely ventrieose, cinereous. Smell faint, nauseous. When 

 young, the whole plant is covered with copious white flocci. 



A very distinct species.
