Another anamorph in Rubus spp.
Josep Torres, 21-05-2025 08:31
Josep TorresReddish-brown, grain-like ascomata, measuring 0.7–0.8 × 0.4–0.6 mm, sprouting in a scattered manner on decomposing Rubus spp. stems.
I have not been able to clearly observe conidiogenesis, although these conidiogenous hyphae do seem to be visible in some of the images, just a few conidia that remind me of genera such as Fusarium or related species, with measurements in water of:
(6.6) 6.7–7.9 (8) × (1.5) 1.7–2.1 (2.3) µm
Q = (3.1) 3.5–4.2 (4.5) ; N = 40
Me = 7.3 × 1.9 µm; Qe = 3.8
Any feedback is welcome.
Thank you very much in advance.
Best regards.

Pycnidial or acervular?

Re : Another anamorph in Rubus spp.
Hi Luc.
It clearly looks like acervulus. I'm adding an image of the section at 100x magnification; it's completely superficial.
Best regards.

Re : Another anamorph in Rubus spp.
Thank you both very much.
I'm leaving the folder as Sclerotiopsis aff. rubi for now. While the leaves are true, I don't think I'll find a better option. Even the conidia measurements are a perfect match.
Best regards.
