Cryptodiaporthe / Plagiostoma ? on Tilia(?)

Hello everybody,
I am not getting on with the following collection:
Substrate: From wood anatomy I get to Tilia, but then, I am not very experienced in wood anatomy...
Macro: Perithecia immersed in bark in groups of 2-8, black, globose, with a diameter of 0.4-0.7 mm, with a long ostiolar neck that is slightly laterally compressed and reaches 0.4 mm in length. No black delimiting zones in wood/bark.
Micro: Asci 60-75 x 8-9 µm, apical ring strongly red in Congo. Paraphyses not seen. Spores two-celled, 18-20 x 3-3.5 µm, hyaline and with a hyaline, pointed appendix of 3-4 µm in lenght on each end.
Maybe I get the substrate wrong which might explain the identification difficulties.
Anyway, I would be very grateful for any hints.
Stefan

Re : Cryptodiaporthe / Plagiostoma ? on Tilia(?)
Dear Enrique, Thanks! Yes I know this. However I keep getting to Tilia. Next best hit until now would be Acer (campestre). But you are right, I should keep working on the correct host!
Best,
Stefan

Re : Cryptodiaporthe / Plagiostoma ? on Tilia(?)
Hi everybody,
Maybe I was a bit lazy first...
After some more work I pinned down the substrate to Acer spec. and ended at
Apiognomonia hystrix (Tode) Sogonov
which fits nicely.
Best wishes,
Stefan
