Nov., 1912.] Concerning Ohio Polyporacece. 23 



herbarium at present. During the fall of 1911 the writer spent 

 several days in collecting in hitherto un visited 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 Polyporacese. 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 11 S 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.
