Closer

The scope views vere like this

The asci were 35-50x5-6, paraphyses may be a little swollen at tips, which were 2-3 wide.
The spores were pretty, (17-) 20-22x2,5-3, very narrow at the other end.
It's a pitty, that my photos doesn't show their beauty.

Hi Marja

Guy recently said that you very probably have a problem with the camera-ocular relation, that you do not get sharp images at oil immersion. I do not have an advice, maybe there is no possibility. Did you change the distance between ocular and front lens? Yor metadata are killed so I cannot see what you have.

Yoru Orbilia is the common O. aristata Velen. Earlier it was determined as O. occulta, but the type is from N-America and differs, e.g., in much shorter spores.

Usually O. aristata is also shorter, about 15-20. At the margin you will find glassy processes which form the small crenulae.

This was probably above the snow :-), is it jnner face of bark? What date?

Hi Zotto,

thank you. :)
I collected this today and it is really on the inner side of the bark. It grow about 1,5-2 m from the ground maybe 1m above the snow level on a 5 mm wide twig. You really know these!
Evenif common, a new species to me :)

I got only a led light on my microscope now, because the transformed is broken. It's not fixed to the tool and that certainly don't make thingsany better...
I take photos straight on the front lens, because the distance to the specimen is allready long.

Do you mean the microphotos? Close to the ocular? I meant did you also test going 1-2 cm away from the ocular? (freehand)

Hi Zotto,

I tried with help of a parer roll, but the photos were if possible even worse,

I've now met this Orbilia on the bark (or phloem) of Salix and Betula, too. So it really seems common ;)
Their spores were not that long, maybe 16-18 micrometers.

Marja

yes, it is Guy's belief that your camera cannot make sharp images :-(
