Orbilia on Tilia (?)
Viktorie Halasu, 21-02-2017 21:29
Viktorie HalasuHello forum,

I got this nice collection but have no experience with Orbilias yet. What characters should I look for, please?
I didn't see those orange particles in excipular cells, but I might be wrong. Asci 8-spored, paraphyses fusiform. 
 
Thank you for any help / advice.

Re : Orbilia on Tilia (?)
Dear Viktorie
this is Orbilia carpoboloides (= Habrostictis rubra, = Orbilia piloboloides, = O. lasia).
It is frequently on Ulmus, but also on other trees. Tilia would be the first time, but couldn't it be possible.

Would it be possible to include your collection data in our monograph? The species occurs across Europe and the northwest of N-America, but we have only scattered  data.

What is the pyrenomycete on which it partly grows?

If you could look at the broken wood of the branch: Ulmus is ring-pored with large pores, Tilia has small scattered pores.

Re : Orbilia on Tilia (?)
Dear Zotto, 
thank you very much! 

The collector says you can of course use it. I'll send you locality data as soon as I get them.
 
I checked the wood structure and you're right, it's not Tilia but Ulmus or Fraxinus. I'll take a photo tomorrow.

The pyrenomycete is not determined yet. However, the photos (made by the collector) are from another twig and this one I was given looks differently (bigger and solitary stromata). I'll try to put it here as well (alas, I have very little practice with those either).

Dear Zotto, 
the wood looks indeed like an Ulmus. I'll try the pyreno.

Yes, it is Ulmus: the small pores of the summertime are arranged in tangential rows. See my arrows.

Dear Viktorie
could you find out the collection data of this Orbilia?
Would be great to get them

Re : Orbilia on Tilia (?)
Yes, I'm only waiting for a herbarium number to be given to that collection. Next week I should get it and then I'll send you complete data, if it's ok with you?
