Any help with this one would be most welcome:
Substrate: Fagus sylvatica deadwood trunk
Macro: Perithecia 0.4-0.6 mm in diameter, black but covered with rust-colored granules. Perithecia singly at the very margin, but soon very densely packed and coalescing thus looking like a Hypoxylon species. Fruitbody yields a reddish brown KOH extract.
Micro: Asci cylindric, inamyloid, 85-103 x 5-6 µm. Spores aseptate, narrowly elliptic, equilateral, brown, smooth, with germ pore on either side, no germ slit observed, 13-16 x 4-5 µm. Perithecial wall composed of very dark colored round to angular, thick-walled cells.
Many thanks and best wishes,
Stefan

Peut-être Biporispora europaea ?
Andgelo
Bravo!

Yes, Biporispora europaea, I am just surprised it never showed up on the forum.
It spreads over old stromata of H. macrocarpum and indeed mimics a Hypoxylon, but is not a Xylariaceae. Unpublished molecular results place it far from this family and make it fairly mysterious.
Cheers,
Jacques
