913. A. (Psalliota) Jerdoni, n. sp. Pileo campanulato obtuso 

 umbonato carnoso ochraceo sicco, squamulis superficialibus niveis 

 secedentibus ornato, epellieuloso ; stipite sericeo - squamuloso 

 cavo ; annulo superiore ; lamellis e pallido brunneis transversim 

 lineatis. 



On fir-stumps. Mossburnford, Nov. 2, 1860. 



Pileus 2 inches across, ochraceous (brown when dry), cani- 

 panulate, obtuse, with a broad umbo, fleshy, minutely rivulose, 

 adorned with superficial evanescent snow-white scales; cuticle 

 not peeling off; stem 3 inches high, 2-3 lines thick, cylindrical, 

 snow-white, pulverulent above, brownish with silky transverse 

 scales below ; ring superior, deflexed ; gills adnate, sending a 

 line down the stem, but not truly decurrent, pallid, then brown, 

 transversely striate. Spores dark brown. 



This fine species is allied apparently to A. Caput- Medusce, but 

 is distinct, as far as I can find, from every published species. 

 It has a close analogy with A. ^gerita, luxurians, &c.

Easily known by the absence of the bitter taste and cinereous 

 tint of the gills. 



915. A. (Hypholoma) egenulus, n. sp. Solitarius; pileo hemi- 

 sphserico expanso ex albido niveo umbonato appendiculato ; 

 stipite subtiliter adpresso-squamuloso fistuloso; lamellis dente 

 adnatis purpureo-umbrinis. 



On the ground amongst grass. Apethorpe, May 12, 1860. 



Solitary. Pileus 1^ inch across, hemispherical, expanded, 

 umbonate, but not decidedly rugose or atomate, of a watery white, 

 when dry snow-white, quite smooth as if delicately gummed, 

 even, except towards the edge, margin finely striate, appendicu- 

 late ; stem 2 inches high, 1^ line thick, attenuated upwards or 

 nearly equal, minutely adpresso-squamose, fistulose ; gills pur- 

 plish umber with a white edge, moderately distant, slightly 

 ventricose, adnate, with a tooth. Spores brown-purple. 



Has exactly the habit of Schseff". t. 205 {A. cernuus) ; but that 

 belongs to a different section. The nearest ally is A. appendi- 

 culatus.
