53 ECOLOGICAL RELATIONS OF THE FLORA. 



On this expedition, owing to the scarcity of fleshy fungi, practically 

 all individuals that were seen were collected and these collections were 

 labelled as to habitat. It was found that the restriction of species 

 to these formations was singularly close and that the appearance of the 

 same fungus in two formations was rare. These considerations seem 

 to add an importance to these lists which ordinary citations of habitats, 

 in which duplication of species is avoided, would not have. Fungi, 

 not only in the mycelium but especially in the sporophore production, 

 are probably more susceptible to the water relation than any other 

 plants so that the limitation of species to special formations is largely 

 due to this factor.
