The apex is still intact. Interesting that the axial canal is so much broader when immature. Thanks!

I think probably not

My impression was that the second one is very immature. Don’t know if there is a real difference in the structure of the asci of the 2 images. Perhaps I am wrong. Difficult getting good photos (at least with my scope) as compared to what one sees when moving the plane of focus in and out.

Nice ascus stains!

Is that second one what they look like after dehiscing?
