conce; downy and rather bulbous where it roots into the wood. Gills 

 narrow, close, quite free, velvety, with tawny pubescence. An ex- 

 quisite species, allied apparently to A. longipes. The gills, as in that 

 species, are densely velvety.

 May ; Waynesville, August, 1844. 



Pileo convexo, umbilicato, tenui, margine striato minutissime min- 

 iato-virgato, stipiteque longo, deorsum tomentoso strigosoque^ aurantiis, 

 viscosis; lamellis distantibus, ventricosis, postice sinuatis, adnexis, 

 aurantiis, coecineo marginatis. — Berk, in Hook. Lond. Journ., v. iv., p. 

 300. 



Pileus rather more than half an inch across, convex umbilicate, 

 orange, clothed with a viscid cuticle, smooth, wrinkled when dry ; 

 margin striate and streaked with vermilion flocci; stem two and a half 

 inches high, scarce one line thick, orange, smooth and viscid above, 

 with a few indistinct darker specks, below clothed with matted tawny 

 down and stigose flocci, string} r , attached to dead leaves, etc., by a 

 creeping, strigose orange mycelium. Gills distinct, broad, ventricose, 

 remarkabh' sinuated behind, adnexed, orange, with a vermilion margin. 

 — Allied to A. pelianthinus. The pileus when dry has somewhat the 

 appearance of A. palmatus in consequence of its viscid cuticle. It 

 must be highly beautiful when fresh.

 leaves, in woods. Wa3 7 nesville, Sept. 3, 1844.f 



Agaricus niger, Schwein — On beech bark. Cincinnati, March 3,

 trees, sticks, etc. Waynesville, Sept. 3, 1844. 



Pileo piano, late umbonato, multicolori, primura purpureo, viscido, 



* The tubers, Mr. Lea observes, resemble the grains at the base of Dielytra cucullata. 



t As the locality is curious, I subjoin Mr. Lea's notes. "Pileus brown, subhemispheri- 

 cal, pruinose ; margin sulcate ; stem buff, very smooth, tapering to the base, much en- 

 larged and spreading into the pileus, 60 as to be clavate ; gills brown, distant, broad, very 

 decurrent." 



I Very nearly allied to A. applicatus.
