Last week, I found what appears to be an Amicodisca sp. growing on what I believe to be Fagus grandifolia (American beech) or red maple leaves, though I can’t be certain as the leaves are quite decomposed. They reach about 300 microns in diameter. Microscopy was done in water and Baral. Any insights on its identification would be appreciated. Thanks!
Take a look at the iNat observations for photos, because I can't seem to find how to upload them here.

Re : Amicodisca sp. ?
Hello, yes, this is clearly an Amicodisca. A. svrcekii seems close, but that has larger spores with a higher lipid content and grows on wood.
There exists a"Trichodiscus" virescentulus (Mouton) Dennis 1963: 374 on Carpinus leaves (Ellis & Ellis 1985: 70 have a sample on Acer leaves.
Possibly the same is Incrupila sulphurea.
Lothar Krieglsteiner made a collection and drawing on Fagus leaves in Kehlheim (Bavaria). See my folder on Amicodisca.

Re : Amicodisca sp. ?
Thank you, Zotto! It does fit, and there is not much information or observations of it on the internet. I see that IF says the actual name is Dennisiodiscus virescentulus. Is this valid? Or should I call it Trichodiscus virescentulus? I will update the species ID on iNaturalist.

Re : Amicodisca sp. ?
The genus Dennisiodiscus is a Pyrenopezizaceae, and Trichodiscus is an earlier but invalid name for Dennisiodiscus. So you may use in apostroph "Dennisiodiscus".

Hi Otto, I got the ITS sequence back from this specimen, here is the Mycomap blast link and the inat link.

Re : Amicodisca sp. ?
Very good! I see a certain similarity with Amicodisca virella and A. svrcekii, but different enough to be a species f its own. The growth on leaves is also different from those.
Do you have the sequence? I would like to include it in a tree. Does it have an exact date?
