Re : Karstenia idaei
Yes, I think it is. I did not see the periphysoids but they are surely there.

Re : Karstenia idaei
Thank you very much Zotto! I will make a picture of the periphysoids tomorrow.

Hi Peter,
Thank you for your help!
I'll try to find these periphysoids.

Re : Karstenia idaei
Are these the periphysoids?

Re : Karstenia idaei
Yes, they are. It is only that the hymenium is not seen which borders at the periphysoids.

Re : Karstenia idaei
Thank you for your help Zotto. I made several samples, but it was difficult to find the periphysoids, but is has been very instructive for me again.
