Hymenoscyphus? on branch of Aesculus - Denmark

Hi
I found these under loose bark on a fallen branch.
Apothecia up to 3/4 mm diam, short-stalked, white to cream-coloured, some turning pale flesh-coloured. Paraphyses slightly longer than asci, tending to stick together slightly, narrowly cylindrical with expanded apex, 2-3 µm wide. In lugol with red circular spots in the upper part. The same colour you see in the excipulum. Asci J+ in apex, 8-spored, 110-130 µm x 10-12 µm. Spores spindle-shaped, perhaps more pointed at one end. With drops, (17.5)19-24(24.7)x 5-6 µm.
Best regards,
Karen P.

Re : Hymenoscyphus? on branch of Aesculus - Denmark
Although white this should be Allophylaria macrospra. What you could check: The living paraphyses should contain elongated VBs (in water, you have VBs in the living excipular cells), and the asci must arise from simple septa.

Re : Hymenoscyphus? on branch of Aesculus - Denmark
Thank you for great help! I have found it before on another tree, Populus, in the same area, so should have recognized it.
The material is from February and dried, so can't check living paraphyses.
