Hypoxylon serpens?
William Slosse, 21-03-2021 10:49
William SlosseGood morning everyone,

a few weeks ago I found this Hypoxylon on a decorticated branch of Quercus robur in the Belgian dune area.
I have no experience with this genus but I think I have to do with H. serpens. Can this be confirmed / corrected?
Average spores size: 11.43 x 4.75. However, width is smaller than the specification in Ellis & Ellis.

Sincerely,
William

Hi William,

You could try to use this key of Nemania genus :

Re : Hypoxylon serpens?
especially you should test IKI (not Melzer) for the pore. N. serpens is unique in being hemiamyloid (red stain).
Best, Lothar

Hi Mirek,
thanks :-)
But I can show a nicer red stain.
