122 FUNGI. [Afjaricus, 



violet- grey then black, stem curved with a broad radiating 

 fibrous base. Desmazieres, Ann. des Sciences, v. 13. p. 214. 1. 10. 

 — Junior. Lycoperdon radiatum, Sow. 1. 145. — Institale radiatum,

On a plastered wall. Holt. Norfolk. — " Pileus 2 inches broad. 

 Gills free, numerous, at first white. Stem \^ inch high, 2 lines thick, 

 cylindric, fistulose, almost equal; curved in consequence of its vertical 

 place of growth, naked, smooth, furnished with a radiating base, 2 inches 

 broad." Desm. I. c. The very curious Lycoperdon radiatum^ Sow. 

 has been determined by Desmazieres to be the infant state of the present 

 Agaric, which is very nearly allied to A. micaceus. The same species 

 evidently, is figured in Pers. Myc. Eur. v. 3. t. 29. f. 4. On carefully 

 inspecting Sowerby's figure, the proper stem will be seen to be very 

 clearly marked out. His observation of its containing a small quantity 

 of fine dust or seed, may perhaps be accounted for by its having sustained 

 some check in an early stage of growth, and in consequence existing in 

 a somewhat altered form, analogous to the abortive plants of A. volva- 

 ceus, which occur under the form of a Sclerotium. 



326. A. macrocephaliis, Berk, (long-headed Agaric^ ; small, 

 pileus elongated at length elongato-campanulate slate-coloured 

 adorned with beautiful pointed scales, gills linear, at length 

 black, stem attenuated upwards fibrillose, fibrillse deflexed. 



On putrid dung. March. Cotterstock, Norths. Rev. M. J. Berkeley. 

 -^Pileus I of an inch broad, | high, linear when young, then cylindrico- 

 campanulate, the margin slightly spread out, adorned with elegant 

 adpressed or patent scales, the remains of the veil ; apex brown, shaded 

 off into slate-colour on the margin, scarcely at all pubescent. Gills 

 linear, perfectly free, at length black, clothed with pellucid spiculas. 

 Stem 1 — 2 inches high, 2 lines thick, ascending, dirty-white, fistulose, 

 clothed with short cottony down and with longer, sometimes deflexed, 

 loose fibres, strigose at the base, somewhat attenuated upwards and 

 stained with the black elliptic sporules. A very distinct species, appa- 

 rently near A. Lagopus. 



327. A. plicdtilis, Sow. (small-plaited Agaric) ; tender, pileus 

 umbilicate sulcato-plicate, gills fixed to a ring round the stem, 

 at length black, stem nearly smooth. Sow. t. 364. With.

Amongst grass. Very common. Spring and autumn. — " Extremely 

 fugacious. Pileus ^ — 1 inch broad, cylindrical, furfuraceous, at length 

 plane, nearly naked, umbilicated, grey, yellowish-brown in the centre, 

 beautifully plicate, membranaceous, pellucid. Gills free, dark-grey, 

 subdistant, very narrow, tender. Stem 1 — 3 inches high, very slender, 

 fragile, smooth, grey tinged with brown sometimes white, hollow."

328. A. Hendersoni, Berk, {delicate-ringed Agaric) ; minute, 

 pileus at first subcylindric at length plano-convex, gills black 

 subdistant, stem furnished with a regular erect subdistant ring.
