Hi Thomas
sorry, but could you provide the spore measurements? :-)

of course - 17.4 x 2.5 µm. I still have the living stuff and can measure more. Just uploaded another pic - hymenium in water.

Yes, a range would be valuable.

The macrophoto by Peter Thompson that I have fits perfectly to yours. Your micros would be the first docu in the living state. Great!

Perhaps you can take a pic also in oil immersion from a living ascus regarding the spores within. They look really broad. described as 2 µm in the dead state, 2.5 is good for the living, or do they perhaps reach 3 µm?

Crystals are totally absent? Croziers?

further uploads now available. No clear crystals seen - no croziers to be seen. See description in previous
