Hymenoscyphus aff subferrugineus 210913 47
Miguel Ángel Ribes, 03-02-2015 20:51
Miguel Ãngel RibesHi again

Another Hymenoscyphus, 2-3 mm, stalked, on small Fgus sylvaticus branchs, from 21-IX-2013 in a very wet place.

Asci 8-spores, euamyloid, with croziers, (111.1) 117.8 - 134.0 (144.8) x (8.3) 8.7 - 10.8 (11.1) µm; Me = 127.0 x 9.8 µm, not very alive, so perhaps bigger.
Spores semi-navicular, 70-80% plenty of big guttules, with a gelatinous cover and sometimes with a small lateral teeth in the obtuse apex, (16.0) 16.4 - 18.3 (19.2) x (4.8) 5.3 - 6.0 (6.4) µm; Q = (2.6) 2.9 - 3.4 (3.6) ; N = 66; Me = 17.4 x 5.6 µm ; Qe = 3.1.
Paraphysis straight, cylindrical and plenty of big VBs.
Ectal excipulum mixed between angular (more at base) and prismatical (more at margin). External layer brown.
Medullar excipulum with textura intricata.

Could you help me to confirm it.

Thank you.

Perfect! And even the spores are correctly oriented :-)
