Hymenoscyphus carpinicola (?) sur vaccinium

sur feuille de Vaccinium uliginosum ce petit disque blanchâtre, sessile. Diametre 1.5mm.
Asques à crochet, 80-90X 12µ. Je ne vois pas de réaction positive au lugol.
Spores 14-20X4µ avec 2 gouttes moyennes et plusieurs petites Forme presque scutuloides
La texture est de forme globulosa!
En suivant la clé de B Declercq je suis arrivé sur Hymenoscyphus carpinicola qui est indiqué comme pouvant venir sur Vaccinium. La fiche de Zotto HB4304 correspond assez bien, mais je suis géné par l'absence de réaction au Lugol, alors qu'elle devrait être RR.
Qu'en pensez vous?
Merci

Re : Hymenoscyphus carpinicola (?) sur vaccinium
Hmm, are the apos really 1.5 mm diam.?
My first idea was Allophylaria (Pezizellaceae), because I supposed to see a distinct stipe.
But this is not clear.
Is your Lugol strong enough? I do not see a yellow medium. Good would be to see the apical ring of a dead ascus in IKI, though my pics of P. carpinicola do not show a strong difference to Allophylaria.

Re : Hymenoscyphus carpinicola (?) sur vaccinium
Thanks Zotto.
I will recheck apical apparatus. My Lugol is 6 month old. Is it already too much?
I did not know Allophylaria. Can you please tell me are the characteristic of this genius? I'm a little bit lost, there is so much to discover!

Re : Hymenoscyphus carpinicola (?) sur vaccinium
My Lugol keeps many years, but sometimes you need to add black crystals of iodine, though I didn't this since years. Good is a glass bottle to avoid escape if iodine.
Allophylaria usually has a gelatinized excipulum but in living samples this may also look like prismatica. The shape of ascus apex is more T- or V-shaped, similar as in Pezicula.
The genus is rlated to Calycina, but not to Hymenoscyphus, though often confused with it.
