Hi to all
We have found these pustulate, ellipsoid, scattered, erumpent stromata up to 18 mm in diam. and 1 mm high on small branches of Juglans nigra lying on the ground. Perithecial necks are black protruding, long cylindrical and furrowed, and the entostroma is pale ochraceous or withish.
Ascospores are allantoid, subhyaline, not or only very pale yellowish, 8.2-10.3 x 1.9-2.4. Asci shortly stipitate with a pars sporifera 25-33, with a conspicuous apical apparatus deeply blue in IKI. Some ascospores (aberrant?) are ellipsoid, not allantoid (marked with white arrow).
I think this fungus could be EUTYPELLA JUGLANDICOLA (Schwein.: Fr.) Ellis & Everh, at least sensu Rappaz (Mycologia Helvetica, 1987), but surprisingly the Index Fungorum says that this fungus is only a synonym of Botryosphaeroia obtusa.
Have you some idea for help me?
Thanks again
it is hard to be sure about E. juglandicola, the morphological features are variable and overlap with those of related species. Eutypella aequilinearis is very similar and perhaps a synonym.
However, juglandicola for a collection on Juglans sounds fine!
Good evening,
Jacques
Merci Jacques
Je comprend qu'il est tres difficile assurer que notre récolte est E. juglandicola parce qu'il est une espece peut etre non bien etudié.
Avec toutes mes amitiés
