Nemania aenea var. aenea?

Hi,I have some problems with this pyrenomycete, which seems to be a member of the genus Nemania. My determination says it is N. aenea var. aenea. Perhaps someone can give his opinion about it.
The spore surface does not have any lines, it seems to be smooth. I have compared my finding with data about N. aenea and with the description of pyrenomycetes.free.fr.
The stroma is only a few mm² and consists of some clustered, 0,2-0,5 mm broad perithecia. The substrate seems to be Fraxinus or Alnus, I am not sure.
thanks and regards,
björn

Re : Nemania aenea var. aenea?
Hi Björn,
your identification seems very plausible. Two additional tips to recognize it are the fairly soft stromata (just weakly carbonaceous) and the short germ slit which is more visible than that of N. serpens. The colour of apical plugs you obtained after a drastic treatment in 20% KOH is interesting. You should try it on other members of the genus, maybe you will find diagnostic reactions.
From my experience, Nemania aenea has a peculiar ecology, I always found it on wood that had been staying in water and then washed onto the banks, anyway never far from water. Is it the case with your find?
Happy new year!
Jacques

Re : Nemania aenea var. aenea?
Hi Jacques,
well I found this Nemania in a very wet lowland forest with Alnus, Salix and Fraxinus trees. The twig was lying between plants not far away from water, this is right.
I have some other Nemania species lying here which have not been determinated yet. I will show them next year :D (perhaps tomorrow).

björn
