Pileo tenui, reflexo, basi effuso, subtiliter tomcntoso, pallido-ligneo, 

 zonis saturationibus; contextu albo; hymenio poroso sinuoso, pallido. 



Pilei effused at the base, reflexed above, laterally connate, at first 

 often attached b}^ the vertex, or triquetrous, pale wood color, finely 

 tomentose, marked with numerous zones which are darker; hymenium 

 pailid, consisting of slightly sinuous pores, about one thirtieth of an

Lenzites Crat^egi, n. sp. — On a dead branch of a Crataegus. Cin- 

 cinnati, Oct. 12, 1840. 



Pileo coriaceo-rigido, glabarrimo, nitido, cervino, concentrice sulcato 

 et fasciato, quandoque radiato-ruguloso; poris flexuosis, clemum 

 elongatis; dissepimentis molliusculis, hie illic lamellseformibus. 



Pile us orbicular, one and a half inches broad, fixed by the vertex, 

 rigid, coriaceous, quite smooth and shining, repeatedly zoned and 

 sulcate; hymenium brownish; pores one sixtieth of an inch in diame- 

 ter, slightly sinuous, much elongated toward the centre; dissepiments 

 thin, soft. This beautiful species has exactly the habit of Hexa 

 gona tenuis, but the pores are very different. It was gathered at 

 Isle aux Noix, Canada, by Dr. Maclagan, by whom it was sent. The 

 specimen is ungulate, and marked with little radiating lines, which are 

 wanting in Mr. Lea's plant.

Pileus three inches broad, convex, smooth, of a tough fleshy sub- 

 stance, at length much cracked and split; margin involute; stem one 

 and a half or two inches high, three quarters of an inch or more thick, 

 buff and split like the pileus; tender when fresh ; spines even, subu- 

 late, entire, soft, of a pale buff; smell vinous. A remarkably rigid 

 species when dry; allied to H. candidum and H. repandum.
