Could this be Lachnum pudibundum?

Yesterday I found these discomycetes with a cup diameter of about 1 mm on wet and rotten Salix wood. Spores measured in water were 7.5-11.5 x 2.0-2.5 micron. Paraphyses were lanceolate and exceeded the asci by 20-30 micron. Hairs had a maximum length of 50 micron, were cylindrical and sometimes had a clavate top. Could this be Lachnum pudibundum?
Kind regards,
Jan

Re : Could this be Lachnum pudibundum?
Yes, possible. Asci lack croziers and apos turn reddish as I see on your pics. The reddish change is due to striking abundant VB-guttules in the paraphyses which are invisible on your picks because of pressure on the cover slip. They would be very characteristic for the species.

Re : Could this be Lachnum pudibundum?
Thanks for your reply Zotto. Unfortunately, I made several other preparations but didn't find the characteristic guttules in the paraphyses. What other Lachnum species could it be if these guttules are truly absent?
Kind regards,

Re : Could this be Lachnum pudibundum?
Made some other preparations today, and to my surprise lots of guttules seem to be present in the paraphyses. Does this confirm L. pudibundum?

Re : Could this be Lachnum pudibundum?
Maybe, although I am not sure if your paraphyses are alive. You may not press on the cover slip, and the apos must be fresh.

Re : Could this be Lachnum pudibundum?
The collected material, a piece of wood with the fungi, was kept at about 20 degrees centigrades under moisty conditions and a preparation was made from a fresh apo. I covered the preparation with a slip and less pressure was applied compared with my earlier preparations.

Re : Could this be Lachnum pudibundum?
I believe you but for the asci they are clearly dead, and with the paraphyses I am not sure.

Re : Could this be Lachnum pudibundum?
It's a pity that we cannot come to a final conclusion as to the identity of this species, but I would like to thank you, Zotto, for your attention and comments.
Kind regards,
