Allophylaria clavuliformis?

Apothecia are < ca 0.5 mm across; pale yellow with a short white stalk. Excipular cells are rectangular away from the margin, longer and thick-walled towards the margin (textura oblita?).
Asci are 110-130 x 7-9 µm; tip turning red in IKI.
Spores are 15-16 x 3.5-4 µm; no septa; with several large oil bodies and many smaller ones; some flattened on one side.
Paraphyses are ca 1-2 µm wide, with slightly swollen tips with conspicuous oily contents.
Because of the ascus reaction to IKI and the excipular structure, I provisionally identified it as an Allophylaria. A clavuliformis seems to be the best fit, but I have very little information on this species. I'd be grateful for any guidance.
Thanks in advance.
Marcus

Re : Allophylaria clavuliformis?
Hi Marcus,
Did you consider A. Byssacea ?
It's not rare in wet zones such as Le Marais Poitevin, and Lycopus europaeus is the most frequent substrate.

Re : Allophylaria clavuliformis?
Zotto - thank you for your help.
How does A. byssacea, which Michel mentions, differ from A. clavuliformis?

Re : Allophylaria clavuliformis?
Good question!
I am unaware of a good redescription. Karsten published it 10 years after byssacea, and perhaps he thought - like me - that on dicots grows another fungus than on monocots.
I first thought the spores are wider on dicots but finally i gave up this distinction.
