Eutypella on Juglans

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

Re : Eutypella on Juglans
It looks like the synonymy in Index/Species Fungorum is based on a misapplication of the name Sphaeria juglandicola by Currey, not the species in its original circumscription. I'll ask Paul Kirk to change it, but it may take a few days for the change to be made. But whether your fungus is identical to Schweinitz's North American fungus, who knows? Rappaz made a really noble effort in her monograph, but there's a lot left to learn....

Re : Eutypella on Juglans
Hola Enrique and Paul,
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


Enrique
