INDIANA FUNGI—V. 
J. M. VAN Hook. 
In the present paper, sixty-eight species are listed. For the most part, 
these have been collected since 1915. While they are not all new to 
Indiana they are new to the species in the herbarium of Indiana University. 
The object here is not merely to make a list of those fungi new to the state. 
but to study independently all those brought to our notice or collected for 
the purpose of study, in Indiana. In these studies, special attention will 
be given to the so-called Imperfect Fungi and to extend the number of hosts 
of a single species. 
The author has appended corrections and additions to the descriptions 
already given, since many of the earlier descriptions are so meager that 
many specimens which should have been referred to them, have doubtless 
been published as new species. These merely needed redescriptions. It is 
the belief of the author that a more critical study of material gathered in 
quantity and in various conditions of development, will go far to discourage 
new species making, as well as to bring about the reduction of the number 
of those already listed. The discovery of new hosts is especially to be 
desired as the form of the fungus may vary considerably with the host. 
The neglect of this careful study in the past has been conducive to the mak- 
ing of new species. While many new species exist, and while we have a 
number for future publication, we have come to believe that we can render 
a greater service to botanical science by extending descriptions already 
published. 
Under those listed, no attempt has been made to give complete descrip- 
tions, but to note the variation from the original descriptions and to ex- 
tend those descriptions. 
When the place of collecting is omitted, it is understood to be Monroe 
County; likewise, when the collector is not mentioned, the specimen was 
collected by the author.
