ADDENDA. 



I have found Lycoperdon areolatum, in Canada ; 

 in esculent qualities, it is nearly equal to L. gigan- 

 teum. 



I have also found near Toronto, a new species 

 of Lactarius. I do not think it has been described 

 before ; and finding it in Canada only, I have pro- 

 posed to name it the Canadian Blue Fungus, LAC- 

 TARIUS CANADENSIS. It is from 4 to 8 inches in di- 

 ameter, the gills are crowded, and run down the 

 ringless stem. The pileus, at first is convex, at 

 length concave ; the plant is firm and woody, and 

 grows in autumn, in pine woods. When the 

 plant is bruised, bright blue milk exudes, which 

 8 >oon changes to green.. This plant not edible.
