Rare Mushroom? AB, Canada

[Ken Sanderson]

Hello!
	Does anyone know of work that has been done (book, papers etc) on 
determining what mushrooms are rare? In particular I am interested in 
Canada and even more interested in Alberta, British Columbia, and 
Saskatchewan. 

	A second related question is: Has anyone ever found Pseudohydnum 
gelatinosum (toothed jelly fungus) in Alberta? If so where abouts in 
Alberta? Also has anyone ever found Amanita muscaria var alba (white 
variety of Amanita muscaria) in Alberta or surrounding provinces? If so, 
where?
