wood, so that only about an inch can properly be called stem. 

 Some specimens approach very near to P. luteus, but the pores 

 in that species are still smaller, in addition to other differences. 



48. Polyporus (Merisma) Berkeleii, Fr. " Latissimus, pileo 

 suberoso tenui utrinque applanato longitudinaliter rugoso [sub- 

 tiliter tomentoso] alutaceo, margine acuto uudulato lobato, con- 

 textu porisque tenellis moUibus insequalibus pallidioribus.'' Fr. 

 Nov. Symb. p. 40. Curt. no. 547. Upper Carolina. 



Yellowish white. Pilei imbricated, nearly a foot long, and 

 more in breadth, thin in proportion to the length, marked with 

 irregular zones and numei'ous radiating ridges and lines, tomen- 

 tose, but not uniformly ; margin thin, acute, lobed and waved. 

 Substance i an inch or more thick, contracting greatly in dry- 

 ing. Pores middle-sized or large from confluence, irregular, 

 angular, sinuated, dissepiments thin. 



Nearly allied to P. lubatus. Substance not friable as in P. 

 sulphur eus when dry, to some specimens of which it bears a certain 

 resemblance, but tough and corky. 



49. Polyporus (Merisma) trichrous, n. s. Csespitoso-multiplex, 

 succoso-caseosus, subtiliter tomentosus hie illic velutinus umbrino 

 pallescens zonatim obscurior ; contextu corneo ; hymenio can- 

 dido, poris minutis subsequalibus angulatis, dissepimentis integris 

 denticulatisque. Curt. no. 2944 . P. tricolor, Rav. no. 973. On 

 old logs, Apr., May, South Carolina, H. W. Ravenel, Esq. 



Pileus many inches broad, stemless, various, mostly dimidiate, 

 with more or less intricate lobes, undulated, rugose, or nearly 

 even, umber-brown, at length paler with darker bands, but not 

 truly zoned, finely tomentose, in parts velvety ; margin inflected 

 or straight. Substance salmon-coloured, becoming white when 

 dry, soft but very tough. Hymenium white, veiy slightly tinged 

 here and there with yellow. Pores minute, g^^th of an inch 

 across, moderately long, mostly equal, angular; dissepiments 

 thin ; edge entire or variously toothed. Smell pleasant ; taste 

 scarcely any. 



This species has very much the appearance of P. snlphureus, 

 differing principally in its umber-brown pileus, salmon-coloured 

 substance, and white tubes. The substance is tough, and not 

 friable. It seems just intermediate between P. sulphureus and 

 P. imbricatus. We have been unable to retain Mr. EavenePs 

 name, as it is preoccupied by Leveille. 



50. Polyporus (Anodermese) Halesice, n. s. Pileo effuso reflexo 

 pallido zonato, zonis obscurioribus ; tomento postice subspon- 

 gioso antice lineatim subfasciculato vestito ; poris minutis cinereo- 

 cervinis. Curt. no. 2027, 2028. On branches of Halesia tetra- 

 ptera, Upper Georgia.
