In the middle of an alder swamp forest, in Belgium, is a dike that the last six months has been inundated by the high water level.
Ascomata was found in November, at the base of a mossy, dead poplar (populus) seemingly growing on the bark.

Apothecium: 14 x 15 mm, saddle-shaped, selliform, grey-green, the brim is not attached to the stipe except one attachment of 0.5 mm wide;
Stalk: dirty yellow, 27 mm long, at the top 6 mm and 4 mm wide at the base, the whole length ribbed, the ribs run 2 mm further on the apothecium;
Spores: elliptical, 15,23-19,43 x 10,36-12,97 µm, Q = 1.53, 1 large drop and several small ones,
Asci: 194,53-261,53 x 16.77-22,17 µm; cylindrical, IKI-;
Paraphyse: septated, filiform, branched and 5 µm wide with up to 8 µm swollen top
Ectal exipulum: textura globulosa-subglobulosa length > 50 µm
Medular exipulum: textura intricate

Could this be Hevella lacunose var. sulcata or is it a H. lacunose that suffered from the wet weather and environmental conditions? Thanks for your help!
