ENDOTHIA PARASITICA AND RELATED SPECIES. 49 
the Gulf of Mexico. There is, however, a very great difference in 
the abundance of this species at different points. In the southeastern 
United States—that is, the region south of central Indiana and 
southern Virginia and east of central Arkansas and Louisiana—this 
species occurs in great abundance wherever its hosts are found. 
‘Broken branch stubs and exposed roots of Liquidambar, Fagus, 
and Quercus are covered with fructifications of this fungus. This is 
especially true of roots exposed by erosion or excavation which have 
suffered mechanical injury through the tramping of men or cattle. 
Farther north in Maryland, New Jersey, and Connecticut only an 
occasional specimen is found. Three days’ search in southern Con-

necticut, for example, yielded only two specimens, both on Liquidam- 
bar, showing pycnidia only. 
Endothia singularis is known at present only on oaks in the dry 
foothill regions of Colorado and New Mexico. Bethel, in a letter, 
states that it is very abundant in certain localities in Colorado. 
Endothia fluens has long been known to occur in both Europe and 
America. Recently, through the kindness of Dr. Y. Kozai, director 
of the Central Agricultural Experiment Station, Nishigahara, Tokio, 
Japan, the writers received four specimens of fungi on chestnut. 
One of these, collected by S. Tsuruta on October 14, 1914, in the 
Province of Totomi, was the pycnidial stage of an Endothia, which 
when cultured proved to be £. fluens. Ascospore material of this 
species has since been collected by Meyer at Nikko, Japan, on the 
bark of Pasania sp.
