Spores and parafyses filled with small refractive guttules. Gelatinous exc. with dark cells. Sp curved fusiform, 18.2 x 2.5; 17.1 x 2.5, 16 x 2.2, 17.4 x 2.5 µm. Asci lugol +++ blue; asci in turg. state (water): 70-75 x 5,5-5,9 µm, without croziers. Paraphyses ± cylindric, ca. 2,2 µm wide.

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
