Bernard CLESSEBonsoir à toutes et tous,J'ai trouvé ce matin ce
Some small pycnidia sprouting abundantly on an acorn on the ground.
Blackish in color like grains, very superficial, poorly adhered to the substrate, with a size between 154.54 to 219.7 µm. wide and with a height of between 70.74 and 123 µm.
Hyphae from the wall of the perithecium are heavily pigmented brown and have a labyrinth-like arrangement.
Cylindrical conidiogenous hyphae with measurements of (10.7) 11 - 22.1 (24.8) × (1.6) 1.7 - 2.6 (3.6) µm.
Cylindrical conidia, many of them tapering, with guttulas inside and measurements of:
(6.7) 7.5 - 9.2 (10) × (2.1) 2.2 - 2.9 (3.4) µm
Q = (2.2) 2.6 - 4.3 (4.6) ; N = 40
Me = 8.2 × 2.5 µm; Qe = 3.3
I understand the difficulty of identifying species like this, but given the specificity of the host, perhaps there is someone here who knows it. It's just that I have the feeling that I've seen it before somewhere, but my memory is no longer enough.
Thank you very much in advance.
Kind regards.
Have you looked at Phomopsis glandicola? Conidia look close also. regards
He was completely unaware of the existence of the species.
There is not much information about the species on the internet but it seems that it would be associated with Quercus, even Quercus ilex.
Microscopy would also fit quite well with your Phomopsis glandicola proposal.
Again, thank you very much.
Kind regards.
Josep.
