APPENDIX. 
Mr. Aage Lund has sent me a list of fungi from Iceland collected 
by Mr. L. Harmsen and Mr.St. Steindérsson. As I have received the 
list at a moment when a great part of the present paper was printed, 
I give the list here as an appendix.

the conidia are much shorter (12—15 yw) than in H. Viole and they are 
never curved.
