Hymenoscyphus?

Found on rotting twigs in wet woodland.
Fruits whitish. about 1.5mm tall and varying in width to about 8mm at the largest. Ascospores approx. 18.2 x 5 microns. Paraphyses seem simple, aseptate, 2.5 wide. Frogot to write down dimensions of asci.. Not a very good description but I was wondering if somebody knows the species as many small ascomycetes have not been documented in my area (Isle of Wight, S England). I thought H. caudatus but the spores do not look right for that.

Re : Hymenoscyphus?
Dear Georges
are you sure wth a twig or could it be a petiole? This is H. fraxineus, in case the asci arise from croziers, or less probably H. albidus (without croziers).
Rarely H. fraxineus occurs on branches, I made a collection recently, but it was immature (see below). Characteristic is the black base and blackened substrate. In the stipe base occur crystals in these two species.

Re : Hymenoscyphus?
It looked like small twigs but I suppose it could be petioles, which would make more sense. Thank you for your help here - I will see if I can get anywhere finding croziers.
