Valencia Lopez Francisco JavierHola amigos/asRecientemente encontré esta colecci
This is an unknown conidioma (may be an acervulum) with long hairs that grew on a dead grass in Castro Laboreiro (Portugal).
It was about 300 microns long and 220-250 microns in height. Black, long, septate hairs covering the whole pycnidium wall (300-560 microns long and 7-11 microns wide).
Conidia hyaline, 11.6-13.7 x 2.5-2.8 microns (without appendices), and up to 26.3 microns including the appendices.
I was thinking on a Colletotrichum species but I've not literature about it.
I will appreciate any suggestion.
Thanks!
Isaac
You can compare your sample with data from next references:

Many thanks for your answer. I've checked the keys provided in the first paper and my samples match quite well with D. strigosum.
Thanks for the literature provided!
Best wishes,
