p. 305. Pileus eight inches broad, four and a half inches long, attached by 



a very short, lateral, disciform stem, flabilliform, smooth, opaque white, zone- 

 less, or with a few obscure depressions and short radiating grooves; substance 

 hard, corky, white, one and a half inch thick, margin subacute ; hymeniura 

 even, of a very pale ochre; pores small, one hundred and sixtieth of an 

 inch in diameter, mostly roundish, here and there forming linear, or curved 

 sinuses. Sometimes the stem is accidentally elongated. Resembling some- 

 what Dcedalea ambigua, and certain states of Lenzites rcpanda, but distinct from 

 either. I am obliged to alter the name, as while my paper was in the press, 

 M. Leveille published a species under the name of Trametes incana. 



' Djedalea ambigua : pileo suberoso, crasso, convexo, azonato, dealbato, 

 glabro; hymenio subaJutaceo; poris parvis, sinuosis, acie obtusa. Berk, in 

 Hook. Journ., vol. iv. p. 305. Pileus sessile, dimidiate, six inches broad, three 

 inches long, one and a half inch thick, venose, zoneless, opaque-white, as if 

 white-washed, smooth or most minutely pubescent, in the younger parts only 

 of a hard corky texture; white within, margin at first very obtuse ; hymenium 

 rather concave, of a pale tan-color ; pores small, narrow, sinuated moderately 



deep ; dissepiments obtuse. Other specimens gathered at Waynesville, 



Aug. 8, 1844, after the above characters were published, approach nearer to 

 Lenzites repanda and L. applanata, combining the characters of both. They 

 are flat and thinner, with the pores less sinuous, and in one specimen not al- 

 together unlike those of i. applanata. The species is, however, more nearly 

 allied to L. repanda. Even in the thinnest specimens, the margin is not acute 

 as in that species. 



2 A resupinate form, differing from the ordinary state in its paler hyme- 

 nium. 



3 Djedalea pallido-fulva : coriaceo-suberosa, pileo dimidiato, subnitido, 

 azono, pallido ; hymenio pallido-fulvo, poris angustis, parce sinuosis rectis. — 

 Pileus one and a half inch long, three inches or more broad; stem less dimi- 

 iliate, even or rather rugged, zoneless, rather shining, at first most minutely 

 pubescent; substance hard, wood-colored; hymenium pale, tawny; pores 



mostly straight, one-sixtieth of an inch broad. A very distinct species, just 



intermediate between Dcedalea and Lenzites. 



* D^DALEA sepium: pileo tenui reflexo, basi effuso, subtil iter tomentoso, 

 pallido-Iigneo, zonis saturatioriibus, contextu albo; hymenio poroso-sinuosoi
