Ascomycete on a herbaceous stem.
Josep Torres, 20-06-2025 08:33
Josep TorresHello.
Small, blackish, mucronated surface grains sprouting scattered on a decomposing herbaceous stem in the soil.
Perithecia are 0.2 to 0.4 mm in size.
Hyphae of the peridium are globose angular in texture and heavily pigmented.
I was unable to clearly observe conidiogenesis.
The structures that apparently appeared to belong to conidia measured:
(4.7) 4.74 - 5.4 (5.5) × (1.3) 1.33 - 1.6 (1.7) µm
Q = (2.9) 3.1 - 3.8 (4.3) ; N = 30
Me = 5 × 1.5 µm; Qe = 3.5
Considering their general appearance and microscopy, I think they could be Entodesmium specimens, which have already collapsed, and what appeared to be conidia could perhaps correspond to fractions of ascospores. I'm not sure if I'm on the right track.
Any feedback from you would be welcome.
Thank you very much in advance.
Best regards.

Possibly a Leptosphaeria anamorph

Kind regards Mathias

Re : Ascomycete on a herbaceous stem.
Thanks Mathias, even Leptosphaeria aff. acuta seems to be a very good option.
Best regards.
