Causes yellow non-hypertrophied spots on the fronds of the host- 

 plant. The intercellular mycelium sends out hyphae between the cells 

 of the epidermis. The asci are much protruding, unusually slender 

 60-75 X 8-9, early filled with conidia which are 4-5 l^ X 0,5-1 1^ (R). 



No doubt the fungus is not rare, but only little conspicuous, to be 

 found June— September.

Both Winter (II ') and Saccardo (Syll. VIII =") include this species 

 and the following one under this name; Rostrup has formerly (80 a^" 

 6^ 83 d ^"5) even included them as also Taph. Sadebeckii, but Rostrup 

 separates them in his later papers (R 91 b 6. 02 a '"^^). It is common 

 all over Denmark on the leaves of Alnus glutinosa in May— Septem- 

 ber causing hypertrophic deformations on them; only a few of the 

 localities have been recorded.
