herbarium at present. During the fall of 1911 the writer spent 
several days in collecting in hitherto unvisited localities. In 
August of the present year four weeks were spent at the New York 
Botanical Gardens where are found a number of collections from 
Ohio. In these ways it has been possible to gain some knowledge 
of the Ohio Polyporaceae. The work is by no means completed. 
But the results are judged to be of sufficient value to warrant the 
publication, in the near future, of a key to the genera and species. 
In the former paper 118 species were listed. This included 
31 species, mostly of the genus Poria, that have been dropped from 
the list. The literature and the herbarium material of this genus 
are so confused that it is impracticable to spend time on them. 
At the present time the list includes 87 species that are known to 
have been collected in Ohio and of which good specimens may be 
found. Besides these, there are 10 other species, never collected 
in the state as far as known, but the geographical distribution of 
which is such as to make it extremely probable that more sys- 
matic collecting will bring them to light. Another species is of 
such doubtful standing as to exclude it from the list. 
It was not within the limits of the former paper to include in 
the bibliography any except the best and most accessible writings 
on the family. The citations in the supplementary list given 
below are to important writings that were examined in making 
out the list of species, but which were unintentionally overlooked 
in preparing the bibliography.
