Orbilia on Sambucus
Marja Pennanen, 09-04-2012 18:43
Hello,

these about 0,2 mm wide Orbilias have spores about 7-8x2 and asci are about 30-40x4.
Paraphyses have swollen heads.

When the preparate was made, a little piece of wood came with the Orbilia.
I found an anamorph swimming besides the wood.
I suppose it is a Tridentaria (or Trinacrium???) and may be connected to this Orbilia.

Re : Orbilia on Sambucus
Dear Marja

 suppose you have Orbilia vitalbae. What kind of Sambucus you have? woody or ebulus? The conidia are a bit narrower in our illustations.  -- Zotto

Re : Orbilia on Sambucus
Dear Zotto,

thank you very much!
Ooh, yes, I'm happy, a new species for me and propably for Finland, too.

This Sambucus, propably Sambucus racemosa is just a bush, kind of a small (2 m) tree and so woody.

By the way the spores look absolutely amazing. It is a pitty, that I can't see all those fine details with my microscope.

Re : Orbilia on Sambucus
For completeness please tell  me the collection data. And: is the core texture of the branch white or reddish? This is a difference between racemosa and nigra.

Re : Orbilia on Sambucus
Hi Zotto,

I collected this on 4.4. 2012 in Outokumpu, at Mökkivaara, ETRS89: 62.72533, 28.99431 (near my home).

The core of the branch is not white, maybe a bit pinkish. I do not know bushes very well, thank you for that piece of information.

Re : Orbilia on Sambucus
I checked Sambucus from internet. The substrate must be Sambucus racemosa because S. nigra does not grow wild? up here.  Birds eat berries and spread the bush.

Re : Orbilia on Sambucus
yes, and it is the reddish inner texture which is typical of racemosa
