Very good drawing of asci! The right one is fully turgescent (in the literature you will rarely find such asci).

For finding a genus it is necessary to see the paraphyses and their contents (in living state). Do you have Lugol (IKI) to test the ascus apex?
Also a median section to see the excipulum is important.
