FUNGUS FORMATIONS.* 



The prevailing xerophytic effect of the conditions upon the green 

 plants likewise shows in the fungous flora on Sand Point. The summer 

 of 1908 was very dry, thus increasing the xerophytic influences and 

 the fleshy fungi were singularly scarce. However, the lists given below 

 show the ecological character of the habitats almost as clearly as do 

 the other plant lists. Such lists of fungi have not often been prepared 

 although the general habitat relation (whether frequenting woods 

 or fields, sandy soil, etc.), have been recorded. The latter kind of 

 records are, however, comparable to the habitat notes given in the 

 manuals of vascular plants, while the former method is an attempt 

 to list the fungi of definite formations. 



*The determinations of fungi are by Dr. C. H. Kauffman of the University of Micliigan unless 

 othenvise indicated. Thanks are due also to Prof. T. H. Macbride of the Univer.«itv of 

 Iowa, and to Prof. Moore of Missouri Botanical Garden for assistance in this connection. Where 

 the determinations were made only in the field, the species are marked with the author's 

 initials.
