sometimes there are one or two concentric furrows toward the mar- 

 gin; I have specmiens that are tuberculose and others that are very 

 rugged and uneven. It varies greatly too in size ; I have perfect 

 specimens from one to seven inches in diameter, though it is com- 

 monly 3-5 inches in width. 



1 have diagnosed the species as appears to me the typical form 

 in this region, retaining Mr. Berkeley's name as exceedingly appro- 

 priate I consider Trametes lactea^ Berk, and of course T. incana, 

 Berk, to be the same thing with the pores all subrotund. Fries 

 evidently had a Trametoid form when he changed the name to 

 Trametes affibigiia. (Nov. Symb. p. 96.) 1 think \.\\a.t D. glaberrifna, 

 B. & C. and Lenzites glaberritna, B. & C. are not specifically diflerent; 

 and so far as description goes Trametes elegans, Fr. and T centra/is, 

 Fr. must be very closely related species. I have no doubt that 

 when this elegant fungus is well known, it will be found to have 

 appeared under many different names. 



2. D. AUREA, Fr. Golden-yellow. Pileus corky-coriaceous, 

 gibbous, velvety, subzonate, uniform in color; the substance yel- 

 low. Hymenium from porose, narrowly sinuate and labyrinthi- 

 form, yellow. 



Upon trunks of oak; rare. Pileus triquetraus, about 2 inches 

 in breadth, the margin tumid. It is said to vary considerably in 

 its color and in the hairiness of the surface. 



3. I). coNFRAGOSA, Bolt. Pileus corky, a little convex, subzo- 

 nate, uniform in color, reddish-brown, wood-color within. Pores 

 from subrotund and flexuous to narrowly labyrinthiform and 

 lacerate, cinereous-pruinose then reddish-brown. 



On the dead branches of standing trees of Cratcegus to/iieiitosa, 

 rarely on other wood. This is another protean fungus which ap- , 

 pears under many different names. See Peck, 30th Report p. 7 1 . 

 The form commonly met with here is the Lenzites Cratcegi, Berk, 

 of Lea's Catalogue. It grows attached by the apex to the under- 

 side of the branches with the orbicular hymenium downward; 

 occasionally I find it dimidiate on the trunk. The pileus varies 

 from I j4 to 3 inches in diameter; it is brown-zonate and concen- 

 trically furrowed and often radiately rugulose or sulcate. The 

 pores at first are essentially trametoid; they become oblong and 

 flexuous at maturity, and lenzitoid only in old and weathered 

 specimens. The form, Trametes rubesa'ns, A. & S., with linear 

 straight pores is rarely met with on branches in wet woods.
