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).

You can compare your sample with data from next references:

26: 205-218.
or

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,
