Hypoxylon?
Per Vetlesen, 04-08-2015 20:38
Substrate: Corylus avellana
Asci cylindric, 8-spored (some 4-spored), the spore-bearing parts Me = 77 x 9 µm, IKI+.
Spores 1-celled, dark, germinating pore almost the whole spore length a bit bent? Me = 13 x 5.5 µm.

I'm just a beginner when it comes to Ascomycetes and even when there are good keys on the Internet, I find it is very difficult to identify species. Anyway, I think this belongs in Xylariaceae in section Hypoxylon?
Microscopic it has much in common with Hypoxylon fuscum, but macroscopically it do not fit?
Many thanks for inputs

Re : Hypoxylon?
yes most likely fuscum, based on the typical ascospores.
Are you happy with your macrophotos? Sure you can do better!
Cheers,
Jacques

Re : Hypoxylon?
Hei Jacques

Thank you for replay
No, I'm not happy with my macrophotos! My only excuse is lack of skill and simple equipment. Picture 3, 4 and 5 are shot with DSLR through stereo microscope and I have great difficulty getting set it into focus and focus area gets very little. I am sorry and will try to improve.
