imperfect fungi on rubus stem

François Bartholomeeusen, 26-12-2016 18:52

Hi everybody,

On an old stem of rubus I found little black bulbs (diameter: 320 µm) that break through the bark. They are sparcely covered with septated hairs (103-150 x 6,38-7,34µm).
They are imperfect fungi, conidia: 4,02-6,13 x 1,17-2,05 µm.
Can anyone help me identifying these ascomycetes?
Thank you very much in advance,

François Bartholomeeusen
