On a twig of Rubus I found these black ones. Ik can't find the genus with this kind of spores. The last picture of the spores is with Melzer. The measure of the spores in water are 16,5 - 20x 6,5-8 µm. They are septated two times with oildrops in it.

Re : on Rubus
Hello Hannie,
La description est très sommaire, plus de détails auraient permis une meilleure
appréciation.
Toutefois j'ose proposer: Melomastia mastoidea (Fr.) Schroeter

Hi,

I see Melomastia mastoidea. I had this one too in austria on Lonicera, probably a preferred host.

regards,
björn

Re : on Rubus
Paul and Björn thank you. I'll try to write some more details the next time. Problem is that it's difficult for me what I have to say about it.
Regards

Hannie

Re : on Rubus
Hello Bjorn,
Oui cette espèce est fréquente sur Lonicera mais ce n'est pas son hôte
exclusif. Je l'ai souvent récoltée sur d'autres supports (feuillus exclusivement
et généralement arbustes ou arbrisseaux).
Cordialement
Paul
