336 MurRILL: POLYpORACEAE OF NortrH AMERICA 
This species is found about old stumps and trunks during the 
autumn. It has been collected three times in as many different 
states. Morgan determined it as P. giganteus Pers., a European 
species which it resembles in habit and coloring. His specimen 
from Ohio is rather small and undeveloped. A still smaller plant, 
only 4 cm. high, is in the Langlois collection from Louisiana. 
The type plants of the species, however, were sent this year to 
the New York Botanical Garden from Pennsylvania by Professor 
D. R. Sumstine. They are large and well developed and show 
both the immature and the mature hymenium in a highly satisfac- 
tory manner. I take pleasure in dedicating the species to Pro- 
fessor Sumstine.

This species is commonly found at the base of oak trees. It 
is very large, intricately branched, fleshy to tough, and usually 
grayish in color. It varies considerably and has several names. 
The European and American forms do not appear to differ very 
much, and I have also been unable to distinguish it in herbarium 
material from such species as P. intybaceus and P. anax, the shape 
of the spores being rather variable and uncertain in this group. 
Quite a full description of the present species is given in the 
Journal of Mycology for January, 1886. Exsiccati are very 
abundant. Most European collectors have distributed it and it 
has been reported from nearly every state in this country, ¢ S» 
lowa, Macbride, Fitzpatrick ; Ohio, Morgan, Lloyd; District of 
Columbia, James; Pennsylvania, Everhart; Louisiana, Langlois ; 
Canada, Dearness. Atkinson, in his Studies of American Fungi, 
discusses the species at length and gives two illustrations of it 
from original photographs.
