Hello,
Found by Laurens van der Linde, March 2020, The Netherlands.
On Rhytisma acerinum, on both sides of the leaf.
Conidia: 19.0-23.9 x 2.7-2.7 µm
Anyone who recognizes these?
Greetings, Riet

Re : anamorph (with dark hairs) on Rhytisma acerinum
Hi Riet
Compare with Volutella.
- maybe Volutella fusarioides?

Hi Mirek,
Thank you very much for your help!
On Mycobank I found this:
Penzig, O. 1882. Funghi agrumicoli. Contribuzione allo studio dei funghi parassiti degli agrumi. Michelia. 2(8):385-508
On page 484: Volutella fusarioides
Too difficult for me .... :-)
setulis = setae???? If so, too short

Re : anamorph (with dark hairs) on Rhytisma acerinum
Hello Riet
yes setulis means "with setulae" (i.e small - though not necessarily short - setae); in Latin diagnoses the ablative case is very much used - a case we do not have in English or Dutch.
See my recent thread about Stearn's "Botanical Latin" https://archive.org/details/BOTANICALLATINWILLIAMSTEARN/mode/2up
I'm afraid that doesn't help you with your fungus though!
Best wishes
Chris
