HYPORHODII. 219 



On the ground. Sibbertoft. Ecciiia. 



Spores rather irregular, 5-7 angled, 10-12 x 6-8 mk. B. Name griseus, 

 grey ; rubellus, reddish. Lasch n. 566. Fr. Monogr. ii. p. 298. Hym. Eur. 

 p. 212. B. & Br. n. 2004. 



483. A. atrides Lasch. Pileus black, fuscous, becoming pale, 

 black streaked, somewhat membranaceous, plane, deeply umbili- 

 cate, striate. Stem somewhat fistulose, pallid, black-dotted zip- 

 wards. Gills deeply and truly decurrent, attenuated behind, some- 

 what crowded, pallid, the black edge slightly toothed. 



It is scarcely to be doubted that it is only a changed state of A. serridatus, 

 to which it is very like, and from which it does not differ except in its paler 

 colour (stem always pallid), its somewhat streaked (not squamulose), deeply 

 umbilicate and striate pileus, and its gills which are almost whitish and very 

 much attenuated behind. 



On the ground. Hereford. 



Not the plant figured by Quelet. B. &> Br. Name dark -coloured. 

 Lasch n. 560. Fr. Hym. Eur. p. 212. Monogr. \. p. 300. B. & Br. n. 1858. 



484. A. atro-punctus Pers. Pileus pale-cinereous, somewhat 

 fleshy, soft, hemispherical. Stem somewhat tough, pallid, shin- 

 ing, with black punctiform squamules. Gills decurrent, arcuate, 

 distant, alternate, cinereous-flesh-colour. 



Gregarious, small. As A. atrides approaches A. serrulatus, this seems to 

 approach A. lappula. 



On the ground. Dinmore, 1882. Oct. 



Name ater, black ; punctum, dot. From the dotted stem. Pers. Syn. p. 

 353. Fr. Hym. Eur. p. 212. C. Illust. PL 343. 



485. A. nigrella Pers. Pileus growing blackish, umbilicate, 

 smooth. Stem short, glaucous. Gills flesh-colour, then some- 

 what cinereous. 



Small, somewhat tufted. 



In pastures. Perth. 



This appears to be quite distinct from A. atrides ; the stem is not nigro- 

 punctate above, nor are the gills nigro-denticulate. B. & Br. Name niger, 

 black. Blackish. Pers. Syn. 463. B. & Br. n. 1651. S. Mycol. Scot. n. 

 266.

 membranaceous, deeply umbilicate or rather infundibuliform 

 with the margin reflexed, remotely striate when moist, flocculose 

 when dry. Stem 2.5 cent, (i in.) and less long, 12 mm. (% in.) 

 thick, stuffed, thickened upwards, tough, smooth, cinereous. Gills
