Josep TorresTiny blackish ascomata shaped like erumpent grains, measuring between 0.6 and 1 mm long by 0.35 and 0.45 mm wide.
Hyphae on the peridium and exciple have an angular texture.
Conidiogenous hyphae widen at their bases and gradually taper, ending in more or less pointed shapes, measuring (17.8) 20.7 - 30.2 (30.4) × (1.6) 1.8 - 2.4 (2.6) µm.
These conidiogenous hyphae produce ellipsoidal, hyaline conidia with one or two large lipid droplets inside. Free conidia with brown intracellular pigment were also observed, which could perhaps correspond to mature conidia.
These conidia measure:
(7) 7.6 - 9.29 (9.3) × (3.6) 4.2 - 5.2 (5.7) µm
Q = (1.5) 1.6 - 2 (2.1) ; N = 20
Me = 8.5 × 4.8 µm ; Qe = 1.8
I am fully aware of the difficulty of identifying species like this, but I will not fail to prove it.
This conidiogenesis vaguely reminds me of genera like Diplodia, but the conidia are too small to even be considered a genus.
Any feedback from you would be welcome.
Thank you very much in advance.
Best regards.
