Hi! Could someone help me identifying this specimen? I was thinking Plagiostoma / Apioplagiostoma, but can't find one that matches the spores I saw.
Growing on overwintered Acer leaves, Quebec, Canada.
Ascoma, 458,7-487,0 x 267,3-314,1um.
Asci inamyloid, 62,2-75,6 x 14,4-15,9um.
Spores, submedian septa, polar appendages, 18,7-21,2 x 6,4-6,7um, appendages 6,7-7,3 x 5,1-5,9um.

Re : Gnomoniaceae
Hi David,
Some lovely photos – well done. In particular, you've captured the appendages beautifully in the India ink; that's some excellent work. Like you, I would conclude that this is a species belonging to the genus Apiognomonia (or perhaps Apioplagiostoma). It is probably an undescribed species. Acericolous species are different. It would be great if you could confirm this using molecular data.Best wishes,
Alain

Re : Gnomoniaceae
Perhaps Apiognomoniia acerina. See Sogonov et al. 2008. Leaf inhabiting genera of Gnomoniaceae. So far not reported from N. America as far as I know.

Re : Gnomoniaceae
I had looked into A. acerina. But it seems that this species is different. Within this family, it is quite common for European species to differ from their North American counterparts. That is why sequencing would be helpful.
