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



often attached by the vertex, or triquetrous, pale wood color, finely tomentose, 

 marked with numerous zones which are darker; hymenium pallid, consisting 

 of slightly sinuous pores, about one-thirtieth of an inch in diameter. Its near- 

 est ally is apparently Dadalea zonata, Schwein. 



' Lenzites Crat^gi : pileo coriaceo-rigido, glaberrimo, nitido, cervino, 

 concentrice sulcato et fasciato, quandoque radiato ruguloso; poris flexuosis, 



demum elongatis; dissepimentis moUiusculis, hie illic lamellaeformibus. 



Pileus orbicular, one and a half inch broad, fixed by the vertex, rigid, cori- 

 aceous, quite smooth and shining, repeatedly zoned and sulcata ; hymenium 

 brownish ; pores one-sixtieth of an inch in diameter, slightly sinuous, much 

 elongated towards the centre ; dissepiments thin, soft. This beautiful spe- 

 cies has exactly the habit of Hexagona 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. 



^ Htdnum diffractum: pileo carnoso-lento, crasso, glabro, alutaceo, mar- 

 gine incurvo, stipiteque: obeso concolori diffractis; aculeis subulatis, integris, 



moHibus, alutaceo-pallidis. Pileus three inches broad, convex, smooth, of 



a tough fleshy substance, 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.
