Amongst leaves and on rotten wood. Rare. Foxhall, near Edin- 

 burgh. Captain Waiich. Bungay. Mr. Stock.—'' Pileus 1 inch or 

 more broad, at length plane, subumbonate, even or obsoletely striate, 

 becoming pallid. Stem long, attenuated upwards, rigid rather horny, 

 incurved at the base and rooting." Fr. I. c. " Root crooked, thick, 

 knotty, sunk about an inch into the earth, and always attached to 

 rotten wood." Wit/i.— Withering' s account scarcely admits of a doubt 

 that he was acquainted with the true plant of Jacquin, though perhaps 

 he confounded with it other garlic-scented species. Greville's plant is 

 certainly this, and not J., porreus, as proved by specimens from himself 

 now before nie. The stem when dry is shining and striate, not dull as 

 in A. porreus. Its horny texture also is very different. 



141. A. olro'dlbiis, Bolt, (black and ivhite Agaric) ; pileiis 

 even blackish the margin and the free gills whitish, stem tumid 

 at the base and strigose. Bolt. t. 137. Fr. Syst. Myc. v. 1. 

 p. 141. Pers. Myc. Eur. v. 3. p. 230. — A. varius, var. 8.

In pastures and on sticks in moist shady places. Aug,— Nov. 

 Purton, 3ISS. Amongst moss about the roots of trees near Halifax. 



Bolton. " Solitary or gregarious, rather firm. Pileus obtuse. Ste?n 



2—3 inches long, sometimes pruinose at the apex." Fr. I. c. 



142. A. filojjes, Bull {thread-stetmned Agaric); pilens obtuse 

 striate livid-brown, gills free white ventricose, stem long even, 

 root hairy. Bull. t. 320. Fr. Syst. Myc. v. ]. p. 142. FL 

 Ban. t. 2022. /. 2.—A. pilosus, Batsch, El. f. 2. 



Woods. Aug. — Oct. Probably not uncommon. Abundant in Scot- 

 land. Klotzsch, in Hook. Herb.— Wmkbourn, Notts. Cottcrstock, 

 ISorths. Pev. M. J. Berkelei/.— Pileus ^ an inch broad, convex or 

 conico-campanulate, striate, livid-brown or umber with a tinge of flesh- 

 colour, striate. Gills free or minutely adnexed, slightly ventricose, 

 white or a dilute shade of the pileus. Stem 2—3 inches long, fistulose, 

 juicy, smooth, except the rooting base which is pilose, livid, dirty- 

 white or brownish. — It is difficult to distinguish this species from some 

 small varieties of A. galericulatus, in which the manner of adherence of 

 the gills varies very much. Similar forms of A. alcalinus are known 

 by their nitrous odour. 



143. A. Iris, Berk, (onany 'Coloured Agaric) ; pileus obtuse 

 striate sub viscid adorned with blue fibrillse, gills almost free, 

 stem fasciculato-pilose. 



Fir stum[)s. Oct. Clifton, Notts.— Fasciculate or scattered, brittle, 

 when young the pileus and stem are bright sky-blue and beautifully 

 tomentose. Pileus | — | of an inch broad, membranaceous, hemisphaeri- 

 cal, obtuse, striate, umber, clothed with blue fibrillse which are glued 

 down to the epidermis, scattered in the centre, thicker and more free 

 on the margin which is slightly denticulate. Gills free or slightly 

 adnexed, linear, pale cinereous, the margin sometimes denticulate. Stem
