Hymenoscypha amentacea, Phil., Brit. Disc., p. 120. 



On fallen male catkins of willow and alder. Spring. 



Closely allied to C. caucus, but distinguished by the 

 elongated, slender stem, paler disc, larger cortical cells, and 

 clavate paraphyses. 



Specimens examined in Phil., Elv. Brit., n. 116, and 

 Fuckel's Fung. Khen., n. 1178.1 



Phillips says the margin of the ascophore is tomentose, 

 the hair-like cells of the margin being 50 X 18 /x, and 

 continuous.
