Contribution to the Myxogasters of Maine. 
By F, L. Harvey. 
The following list includes all the species of slime-moulds 
known by the writer to have been collected in Maine. 
Species recorded by Saccardo, Massee and Lister are noted. 
We have had accesses to Sprague’s lists; the collections in the Port. 
S. N. H. determined by Cooke and Berkeley, a list of Maine fungi 
collected by Rev. J. Blake, specimens in the Blake Herbarium of 
the Maine State College; and a list of specimens collected at 
Rangely and Bar Harbor by Dr. Rex. The specimens collected 
by the writer have all been examined by either Wingate, Peck, 
Ellis, Rex or Morgan, or carefully compared with authentic speci-_ 
mens. We will be glad to know of additional references or the 
names of past or present Maine collectors of these forms. The 
list is by no means exhaustive, as each year brings to light new 
and interesting forms. Dr. Rex said “ your second sending con- 
tains an unusual number of interesting forms and suggests that 
there may yet be many treasures found.” 
We are under great obligations to the above named specialists, 
especially to Mr. Wingate, from whom came the original inspira- 
tion to study and collect these forms, and to Dr. Rex for many 
kind letters and the determinations of specimens, and since his 
death to Mr. Morgan for similar favors. We have followed the 
order of genera given in Lister’s recent monograph.
