DECADES OF FUNGI.

Hab. Oa the ground, fanure. February, 1853. 



Pileus 1|- inches or more across, cyathiforra, with the margin in- 

 flexed, dark cinereous, rimoso-striate. Stem 4 inches or more high, i 

 thick, smooth, attenuated upwards, of the same colour as the pileus. 

 Gills nearly white, moderately broad, rather distant, decurrent. 



Allied to A. cyatMformis, but a far taller species, with nearly white 

 gills, and remarkable for its rimoso-striate pileus. 



503. A. (Clitocybe) nidis, n. s. ; pilco irregulari subcarnoso sulcato 

 rugoso ; stipite elongato torto ; lamellis crassis distantibus veutricosis 

 decurrenti-adnexis armeniacis. Spruce, n. 137. 



Pileus li inches across, irregular, strongly sulcata and transversely 

 rugose, ochraceous. Stem 4 inches high, i thick, twisted, paler above, 

 reddish-brown below. Gills broad, distant, ventricose, yellow, emar- 

 ginate behind and very slightly decurrent. 



This species has exactly the habit of A. laccatus, but is evidently a 



very distinct species. 



503. A. (Omphalia) smaragdinus, n. s. ; totus viridis; pileo tcnui 

 fortiter umbilicato ; stipite gracili filiformi sequali ; lamellis tenuibus 

 paucis decurrentibus. Spruce, n. 8. 



Hab, On the ground. Panure. 



Green. Pileus I an inch across, thin, deeply umbilicate, almost in- 

 fundibuliform. Stem 1 inch high, i Une thick, equal, smooth, attached 

 to the soil by a few wlute threads. Gills moderately broad, subtrlan- 



gular, distant, decurrent. 



The gills of this pretty species are far thinner than in any form of 

 A. umhelUferus, and the habit more delicate. There is no doubt that 



it is a very distinct species. 



504. A. (Omphalia) euomphalus, n. s. ; pileo umbilicato tenui striato 

 cinereo-albido ; stipite gracili sursum dilatato lineato-striato ; lamellis 

 latis decurrentibus albidis. Spruce, n. 122, 133. 



Hab. On the ground. Panure'. February, March. 



Pileus l-li inches across, cinereous -white, deeply umbihcatc, thm, 

 striated. Stem U-2 inches or more high, dilated upwards, umber 

 when dry, fibrillose or lineato-striate, composed of fibres. GiUs broad, 



dirty-white, decurrent. 



A beautiful species and evidently very distinct. The pileus m the 

 dry plant is deep rufous-brown. The specimens, under the two imm- 

 bcrs specified above, were gathered at different times, and the latter 

 are much the largest.
