Re : Orbilia on Fraxinus twig
Hi Robin

This is probably O. phragmotricha. When you study the margin you will find thick-walled septate hairs. Important is thyt they do not have a long glassy cap on top. Then it would be O. rubella which has also longer spores.

Dear Hans-otto,

Thank you for the answer.

O. phragmotricha is new for Sweden i think.

I could not se any caps, but it would be good with confirmation.

Best regards,

Robin

Re : Orbilia on Fraxinus twig
Exactly! There are low caps subapically or laterally, but never longer than wide. 100% phragmotricha. I think in Skaane I only had O. rubella.
