Quelqu'un d'entre vous pourrait-il me fournir une représentation (photo ou dessin) d'une conidie de
Orbilia oxyspora (= sambuci)?
D'avance merci.

Re : Documentation
Bonjour Camille
How did you arrive at the name Orbilia oxyspora without consulting my homepage folder?
There you could have seen conidia. We consider O. fimicoloides a synonym, here the plate of Webster et al. attached.

Re : Documentation
Guten Tad und vielen Dank Zotto.
I found this strange "thing" in a slide of what I though it could be Orbilia auricolor but I didn't pay attention of what it could be.
Then I read in a forum discussion that you pointed a difference between O. auricolor and O. sambuci based on the shape of the conidias and the resolving of the cells on the edge and I remembered then what I found previously.
I also mesured the spores a little bit longer (up to 14,5 µm) but these could be stretched.
Kind regards.
Camille

Re : Documentation
Hello Zotto.
Herewith some more photos.
Could it be O. sambuci or O. aurantiorubra?

Re : Documentation
Spore shape reminds me of O. aurantiorubra. but spore orientation looks wrong at first glance. Your section in water is good but more photos are needed to better see the spore bodies and perhaps SCBs in the excipulum. The yellowish apo is another species?

Re : Documentation
Both apo's were on the same wood but the micro comes from the paler one.
I'll try to give other photo's.

Re : Documentation
Herewith more photos of spores in water.
The apo's left from the host becomes yellowish.
The conidias seems to come from Diatrybe bullata...
I assume that it will be definitely O. aurantiorubra.
Regards.

Re : Documentation
Yes, it is. The host is often Salix or Ulmus, do you know it here?

Re : Documentation
It seems to be Salix.
Thanks.
Thanks.
