Ascospores fossilised in Sumatran amber
Hans Halbwachs, 10-03-2019 09:17
Dear all,
I would like to ask the community to help me narrow down the taxonomic position of two ascospores. 

I would already be happy with any suggestion/idea about the class or order.

Thank you in advance, Hans

No, but you can forget definitively Polycoccum for the second one. Please in that case not that spores are distoseptate. You can add Cordana pauciseptata.
