pyrenomycete from the Algarve (Portugal)

... growing on small thin twigs of likely Alnus glutinosa near Aljezur (West Coast), on 2.4.2019. THe spores are about 10-12/4-5 µm, the perithecia with a quite conspicuous ostiolum remind a bit of a Gnomonia or similar fungi.


Who can provide me with an idea?


Best regards, Lothar

Hi Lothar
Look for Diaporthe. Very important is to look for ventral black lines in the sustrate.

Hello Enrique,


sorry- it took a long time till today I had the time to have another look at the specimen.


You were fully right. Not only is the surface of the small twigs stained blackish; the stromatic lines are also present.


So Diaporthe spec. - thanks again.


Best regards, Lothar
