Hymenoscyphus phyllogenus

"Hello everyone,
I'm relatively new to microscopy (only about 15 months of experience).
I recently found a fungus that I identified as Hymenoscyphus phyllogenus, but I haven't received any confirmation or feedback here in the Netherlands.
Unfortunately I no longer have the specimen/material.
This is a new group for me. Was I on the right track with this identification, or could it be something else?
Any help or second opinion would be greatly appreciated!"

Mark Stevens, Holland

Hallo Mark,

You did not ask me.

this is something elementry different, it is Rutstroemia sydowiana, Rutstroemiaceae  have a comlete different ascus apical apparatus with a widening at the top and a smaller widening below in Iodine solution. 

Groeten,

Stip
