Hymenoscyphus on Juniperus

as I mentioned I found something on the needles and twigs of Juniperus, which I naturally couldn't determine.
These are about 0.3-0,7 mm wide and 1-2 mm high.
The base of the stipe may be darker.

Re:Hymenoscyphus on Juniperus
The spores are multiguttulate, 12-17x3-4 and asci 75-95x6-8, IKI+.
Paraphyses are septate, some with VB:s and 2-2,5 micrometers wide.
Poor photo of the shape of the spores:

Re:Hymenoscyphus on Juniperus
Another view of microscophy.
Why are these Hymenoscyphuses so hard fo me to open?
I've been able to determine lately only H. kermesinus, H. scutula, H. salicellus and H. caudatus, which are allready quite familiar to me.

Re:Hymenoscyphus on Juniperus
Hymenoscyphus is one of the most difficult genera. especially those with scutuloid spores are a hard nut. I do not see clear in such species like H. caudatus and even H. scutula.
Yours has quite narrow spores, and at the moment I have no suggestion, sorry. Important would be to know the croziers, actually. The ascus base is quite well seen on your photo, but should be viewed with oil immersion. I am sure you can learn that, I also must often search some time to see the feature clearly. It depends on the orientation, on the living state, on maturity etc., all this can obscure the feature. Best is to make a section and look at living cells.

Re:Hymenoscyphus on Juniperus
Hello Zotto,
my problem is that I've got almoust no practical education to mycology or nothing else, too.
I've just learned myself on the way.
Just dived (fast and deep?) into it and hoped to survive ;).
Now I'm waiting in despair, when the local university needs my loaned microscope for educational purposes.
