INDIANA FUNGI—VI. 
J. M. VAN Hook. 
The first paper of this series on the subject of Indiana Fungi,* 
which was undertaken in 1910, was a mere list of those fungi which 
appeared to be, for the most part, new to our State. In the five papers 
previously published, we have recorded 724 species. In the later papers 
we have gradually added more data concerning each species, in many 
cases now entirely rewriting descriptions. Where only fragments of 
descriptions are given, it is to be understood that such fragments are 
additions to, or differences from, the original. 
Investigators, particularly in the field of the so-called Imperfect 
group, are amazed at the many meager descriptions by which one is 
expected to identify his specimen. If the host were unknown, it might 
easily be placed under any one of a dozen species. Spots are often 
described as “epiphyllous” or “hypophyllous” when it is very evident 
that the writer had in mind “pyenidia,” ‘“acervuli” or “conidiophores.” 
It is very evident that spots on living leaves are practically always 
amphigenous, but differing sometimes only in color. The character- 
istics of spots both on the upper and lower sides of leaves should be 
described. 2 
Much new, rare or extraordinary interesting material has been made 
available by Mr. H. M. Hudelson, who is collecting particularly the 
fleshy and woody forms. 
Where the name of the collector is omitted, it is understood to be 
that of the writer; when the locality of its occurrence is not given, it 
is to be presumed that it was collected in Monroe County.
