There is a difference of opinion as to the spermogonia form 

 of this species. Phillips describes it as follows : " Spermo- 

 gonia intermixed with the above [ascigerous form], puncti- 

 form, black, acutely umbonate ; cavity simple, sinuous, 

 narrow ; spermatia filiform, slightly bent, about 10 x 1 /x." 

 This agrees with the description of the spermatia as given 

 by Tulasne, Sel. Fung. Carp., iii. p. 136.
