Pyrenomycete closely packed
Maren Kamke, 22-06-2013 12:50
Maren KamkeHi everybody,
it should be something easy, I thought...

Closely packed together are the perethecia 0,8 mm wide, on wood (angiospermae).
They are located on a bed of dark brown hyphae.
Spore light brown, 1-septate, becoming 3-septate, filled with guttules, (31-38) 33,9 x 7,18 (6-8) µm. Asci 156 x 13, IKL negative, paraphyses filiform.

Thank you for your help.
Regards
Maren

Hi Maren,


seems to be Herpotrichia macrotricha ;)

Byssosphaeria schiedermayeriana is also very close, but I think this species has only one septation...perithecia should have a pale ostiolus.

Hi Björn,
thank you very much.
This is Byssosphaeria schiedermayeriana. I checked the descriptions, the spores get 3-septate with age.
Have a nice midsummer
