Endothia gyrosa. We have examined ascospore specimens of 

 this species on Castanea dentata from several southern states; 

 on Castanea sativa from two sources in Italy; on Quercus alba, 

 O. velutina, Quercus sps. from several localities in America; on 

 Quercus sp. from Italy; on Carpinus Betulus from Tiflis, 

 Russia ; on Carpinus sp. from Italy. So far as we can tell from 

 a microscopic examination, these all belong to the same species, 

 though there is some slight variation of the ascospores in the 

 different specimens. These ascospores vary from elliptical 

 oblong to narrowly oval, often tapering to one or both ends, 

 have an evident septum, and are chiefly 6-9 /x long x 2-3.5 P 

 wide. They are therefore quite distinct from those of the 

 preceding species (see Plate XXVIII b, e). Saccardo gives 

 Aesculus, Alnus, Corylus, Fagus, Juglans and Ulmus as reported 

 hosts for this species, with a distribution including North 

 America, Europe, Ceylon, and New Zealand. But a careful 

 comparative examination would be necessary to state positively 

 that these all relate to the same fungus. 



We have made cultures of this fungus from many different 

 sources on chestnut and oak from the South, and on chestnut 

 from Italy. See Plate XXVI 7590, 7584. While these show 

 some slight variations, they have a general agreement, but 

 differ decidedly from all cultures of the true chestnut blight. 

 We have made inoculation tests, and have found the fungus
