Miguel Ãngel RibesGood night friends

I have this Rosellinia at sea level, in dunes, 28/1/2017, growing at small branchs of Bufalaga marina (Thymelaea hirsuta), up to 1,5 mm wide, not sure about presence of subiculum.

Asci 8-spored, with croziers, IKI+, apical plug with urn-shape, (5,4) 5,9 - 7,5 (7,9) × (3,6) 4,1 - 5,2 (5,5) µm; Q = (1,1) 1,3 - 1,7 (1,9) ; N = 28;Me = 6,7 × 4,5 µm ; Qe = 1,5.

Spores eliptical-fusiform, sometimes with a more or less flat side, 2 big guttules, 2 appendages at both ends and with an incomplete sheat, straight germ slit extending over the whole length, I think at the convex side, (16,2) 17 - 21,4 (24,9) × (6,9) 7,2 - 8,5 (9,3) µm; Q = (2) 2,1 - 2,8 (3,6) ; N = 63; Me = 19,4 × 7,9 µm ; Qe = 2,5.

In picture nº9 I have write "v" in germ slit "ventral" and "d" in germ slit "dorsal".

With Petrini's key, depending on the interpretation of subiculum, I arrive to Aquila group (R. aquila, akulovii or bonaerense) or Mammaeformis group (R. subsimilis or conferta), but I tkink this fits Ok with none.

Could you help me, please?

Best wishes.
