On hedera leave we saw these round structures with a mass of (conidio?) spores with one large droplet, measured in water: Me = 7 × 4.4 µm ; Qe = 1.6

Could this be the anamorph of Hypoderma hederae?
I found this drawing (last picture) on the internet with a similar structure at the bottom left:

Thanks in advance, Margot&Geert

Re : On Hedera
Hello,

Probably the anamorph of Trochila craterium: https://www.centrodeestudiosmicologicosasturianos.org/?p=8272

I recently found it in Belgium.

Re : On Hedera
Thank you very much Luc for the suggestion, it seems to fit well with the conidia size.
Kind regards, Margot&Geert
