Dear Forum,On decorticated wood of Castanea,I foun
I found this Pyrenomycete growing on hardwood, probably Salix.
Perithecia have a size of approximately 0.5mm.
Asci of 120-140 x 13-15um
Spores of average size: 26x13um. When mature they are dark brown.
Do not know what species it is. May belong to the genus Didymosphaeria?
Can someone help your determination?
Thanks in advance.
Susana
Hi Susanna,
Ascospores are incredible, what a nice fungus ! I don't know it, unfortunately.
I hope for you that it will be recognized.
Alain
I keep waiting that someone identifies the species.
At least someone confirm or not genre, because I doubt that the species is Didymosphaeria.
regards
Susana
this is usually referred to as Dothidotthia ramulicola. I found it frequently in the nineties. The ascospores often remain hyaline for a long time under unfavourable conditions.
Cheers,
Walter
