Good afternoon everyone,I found following species on previous year's petioles of Fraxinus.
At first sight I thought this could be Rutstroemia luteovirescens but because of the short stalk I changed soon my vision.
Spores 18.75 x 4.55 um
Paraphyses filiform & septated
Asci I+ and with (?) crosiers
Thx for your confirmation,
William

Re : Hymenoscyphus albidus?
Hi William,
H. albidus has become as you may know far less current now in europe than the macro replica looking H. fraxineus (T. Kowalski) Baral, Queloz & Hosoya 2014. Both have the same substrate
It is essential to make sure whether there are croziers or not as albidus has none. I cannot surely tell from your pictures whereas the spores dimensions would fit for H. albidus.
Amitiés. Michel

Re : Hymenoscyphus albidus?
Looks like a crozier in the lower left corner of image 7. But, indeed, better pictures of attached ascus bases are needed.
The ash dieback arrived in Belgium at least in 2007. So H. fraxineus is very likely.

Martin
