Specimen examined from Fuckel's Fung. Ehen., n. 1095. 



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 10x1 p<" 

 This agrees with the description of the spermatia as given 

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



Coccomyces quadratus. Karst., Myc. Fenn., i. 

 p. 255 ; Eehm, Krypt.-FL, Disc., p. 79.

 then splitting into several acute teeth and exposing the pale, 

 yellowish disc, 1-2 mm. across ; asci clavate, stipitate, nar-

 in a parallel fascicle, paraphyses slender, almost cylindrical, 

 up to 3 p. thick, straight, colourless.
