 inycelium abundant, persistent. Perithecia numerous, scattered

 times diameter of peritlieeium, woven with the mycelium, col-

The specimens on Xanthium Canadense collected at Auburn, 

 No. 1018, seem to agree with Eryslphe spadlcea B. & C, except 

 that the perithecia are gregarious, and the spores vary to less 

 than four. Berkeley's description is as follows : 



"Perithecia scattered, rich brown, ap[)endHges flexuous, three times longer 

 thaii tiieir diameter; sporidia f mr." On leaves of Xanthium, Car, Inf. 



The notes taken from my 1018 are as follows: Amphigenous; 

 mycelium persistent, abundant, perithecia gregarious, 120-140, 

 appendages two to three times diameter of perithecium, woven 

 with the mycelium; perithecia and appendages rich chestnut 

 brown. Asci six to ten, 30-40x60-70, })eclicellate. Spores 

 ' two to four, very often four, variable in size. For several of 

 the first examinations the spores were quite uniformly four. 

 Recognizing this variability which is known to occur in the spe- 

 cies there is no reason why E. spadlcea B. & C. should not belong 

 to this S})ecies. 



E. LiRIODENDRI Schw. 



I Good specimens of this species were collected in the autumn of 



1888 at Columbia on young twigs of Lirlodendron tuliplfera. 

 The mycelium was very abumlant both on the leaves and twigs.
