Lars Romell has stated (92) that Valsa eutypa Nke. is to be divi- 

 ded into two different species: Valsa eutypa on Acer and Fagus and 

 Valsa sparsa on Populus. 



Fagus silvatica. L. Stenskoven (Aug. 05). Acer pseudoplatanus. S. Hareskoven ! . 



1127. Valsa stellulata Fries S. V. "", Wt. II '"'", Syn: Sphaeria stel. 

 Fries S. M. II ^8°, Eutypella stel. Sacc, Syll. I '*'. 



Ulmus montana. J. Frederikshavn ! ; S. Charlottenlund (Sarauw), Sonder- 

 marken, Sore (April 80 Sarauw), Slagelse!. 



1128. Valsa prunastri Fries S. V., Wt. IP"", Syn: Sphaeria prun. 

 Pers., Fries S. M. II '^o, Eutypella prun. Sacc, Syll. I '"'', Slaaens Stev- 

 kugle (H. 37 '«"). 



Rostrup (02 a ^^^) considers this species a true parasite. Foul Larsen 

 has also told me that he has observed that this species has killed 

 large branches of sound trees. 



Pranus cerasus. J. Viborg!, Brabrand (P. L.). Pvunus spinosa. S. Hellebaek 

 (O. R.), Charlottenlund (^/b 81 Sarauw), Sora (Sarauw) ; B. Almindingen. (Exc. 

 15/6 11). 



1129. Valsa ceratophora Tulasne, Syll. ^''^ Wt. II ™l 

 Pranus spinosa. J. Krabbesholm Skov ('"A 04!); S. Ruderhegn!. 



1130. Valsa microstoma Fries S. V., Syn: Sphaeria mic. Pers., 

 Fries S. M. II ^^\ 



Prunus spinosa. S. Ermelunden (''/2 82 Sarauw). 



1131. Valsa leucostoma Fries S. V. ^''\ Syll. I '^^, Syn: Sphaeria 

 leuc. Fries S. M. II ^", Valsa Persoonii Nke., Wt. II 7^^ Hvidmundet 

 St0vkugle (H. 37 ««i). 



Aderhold (03 a) has made splendid and accurate cultivating experi- 

 ments to prove the genetic relation between the Valsa and the Cyto- 

 spora which attack Prunus cerasus, but unfortunately he has been 

 unable to determine the names of the species with which he has wor- 

 ked; he himself, states them to be Cytospora rubescens and Valsa 

 leucostoma, I should, however, consider them more likely to be Cy- 

 tospora leucostoma and Valsa leucostoma. 



Prunus padus. F. Klingstrup; L. Skjelsnaes. Prunus spinosa. S. Sore (Sa- 

 rauw). Sorbus aucuparia. S. Geelskov (O. R.).

 pentagona Fries S. M. II "% Eutypella pent. Sacc, Syll. I ''*\ Rennens

Very common on twigs and branches of Sorbus aucuparia.
