438 Rev./M. J. Berkeley and Rev. M. A. Curtis on new 



bido-fulvo subtiliter tomentosOj margine hispidulo scabriusculo 

 involuto ; lamellis subdistantibus postice attenuatis concoloribus. 

 Curt. no. 2862 ; Rav. no. 1349. On the putrescent stumps 

 apparently of Nyssa ; also on Salix nigra, H. W. Ravenel, Esq. 



Smell strong alliaceous, highly offensive. Pileus 2 inches or 

 more across, stemless, suborbicular, at length slightly elongated, 

 minutely tomentose behind, more distinctly so in front, where it 

 is sometimes rather scabrous and hispid, dirty white inclining to 

 tawny or yellow, especially towards the edge ; often moi*e or less 

 effused behind. Gills of the same colour as the pileus, distant, 

 entire, moderately broad, attenuated behind, interstices even. 

 Spores white with a very slight yellow tinge, minute, oblong, 

 strongly curved. 



A fine species, apparently allied to P. fcetens, but without the 

 least trace of a stem. The curved spores are very remarkable. 

 In the young plant the pileus is nearly resupinate. 



35. Xerotus lateritius, n. s. Pileo sessili reniformi convexo 

 lateritio ; lamellis paucis atro-fuscis. Curt. no. 2563. On damp 

 decayed logs, Dec, Santee Canal, South Carolina, H. W. Ra- 

 venel, Esq. 



Solitary. Pileus reniform, attached by a little down, convex, 

 deep brick-red, ^ of an inch across; margin involute. Stem 

 obsolete. Gills few, dark brown, radiating from the point of 

 attachment. 



Resembling X nigrita, Lev., but distinguished at once by its 

 brick-red pileus. Dr. Leveille has sent us either the same or a 

 closely allied species which he received from the southern part 

 of Chili. 



*Xe7-oius nigrita, Lev., Ann. d. Sc. Nat. Feb. 1846, p. 120; 

 Curt. no. 2868 ; Rav. no. 892, 917. On fallen trunks of Laurus 

 Caroliniensis, Rhus toxicodendron, and Rhus radicans. South Ca- 

 rolina, Feb.-May, H. W. Ravenel, Esq. 



Tawny or brownish when dry ; there is a very short lateral 

 stem, as is also the case in Dr. Leveille's authentic specimens 

 from Manilla, gathered by Perrotet. This at first resembles A. 

 niger, Schwein., but is in reality very different. 



Apparently a distinct species, strongly grooved and thinner 

 than X. nigrita, occurs on dead stems of Vine, no. 1975, but un- 

 fortunately perfect specimens have not at present been gathered. 



36. Lenzites rhabarbarina, n. s. Fulvo-rhabarbarina ; pilea 

 sessili reniformi sulcato-zonato rugoso spongioso velutino ; mar- 

 gine acutiusculo ; lamellis dentatis subsinuatis. Curt. no. 3849. 

 On pine stumps, South Carolina. 



Pileus 11 inch across, scarcely | inch long, of a rich tawny, in- 

 clining in parts to rhubarb-yellow, sessile, reniform, rather thin, 

 coriaceous, marked with two or three irregular furrows, and rough
