Small black pycnidia on Angelica sylvestris

I found today small black pycnidia in the cuticle of the overwintered dried stem of Angelica sylvestris.
Here is photo's and microfotos. First three microphotos - in the pure water, next three - in Mlz.
Size of pycnidia is up to 0.4 mm.
Conidia size:
(4.00) 4.50 - 5.49 (5.61) × (1.44) 1.60 - 2.03 (2.45) µm
Q = (2.25) 2.46 - 3.07 (3.63) ; N = 64
Me = 4.91 × 1.83 µm ; Qe = 2.70
Q = (2.25) 2.46 - 3.07 (3.63) ; N = 64
Me = 4.91 × 1.83 µm ; Qe = 2.70
Please help me with identification. This is very common fungus on this host. It appears each spring with thousands pycnidia. The only one my variant was Diaphorte angelicae, but here is no conformity - this is not this species.

Re : Small black pycnidia on Angelica sylvestris
May be this is anamorph of Leptosphaeria acuta (Phoma acuta (subsp. errabunda?)) ?
