Diaporthoid fungus - need help in identification
Ivana Kusan, 30-05-2012 16:03
Dear Pyreno-friends,

Does anyone have an idea what this fungus might be? Substrate is decorticated trunk of Fagus sylvatica in a forest of Abies alba, Fagus sylvatica, Acer pseudoplatanus and Picea abies. Living ascospores measure 11,7-16,5/6,3-7,1 microns. Spores rapidly die in IKI and are 4,5-6,0 microns wide. Visibility of the apical ring was only enhanced by IKI in water but seemingly with only grey shade and without blue colouration. We consulted Munk (1957), RWG Dennis (1980) and Wehmeyer (1933).


Nice regards to all,


Ivana

Dear Ivana


I think, you have Eutypa flavovirens with associated fungicolous fungus Didymosphaeria conoidea

Re : Diaporthoid fungus - need help in identification
Dear Alex,

:-))) Thank you for your help! When we cut stroma with perithecia we thought it is Eutypa flavovirens because of the green colour. But, we didn't see any Eutypa spores! Only this Didymosphaeria.... It's obvoius now why we couldn't find anything with these characters in the literature.
 
Best regards,

Ivana

I do not think this one is Didymosphaeria conoidea. The species grows on or in old Leptosphaeria (doliolum) fruitbodies and has smaller, brown ascospores. I have found it once (see attached photo).

regards,
björn

Hi Björn,

Thanks for your kind reply. All spores were hyaline and smooth. ?Also quite larger than in description attached by Alex.
