Nitschkia

Hi allI have collected a Nitschkia? near Sheffleld (Yorkshire), on attached branch of a dead Betula standing in a swamp, with aseptate curved biguttulate spores *11-14 x 3.5-3.8 µm, 8-spored asci, and rather small almost smooth apothecia.
N. confertula would be a choice, but the spores are perhaps too long when I compare Virginia's key (Mycologia 96, 2004, p. 915). I did not yet look at the subicular hyphae which are not evident on the macro.
Any idea?

Re : Nitschkia
Hi Zotto,
Yes spores too long for confertula, too wide for cupularis... perhaps closer of cupularis than confertula ?
If the outer cells of the peridium are prolonged into pointed spines, it could be N. brevisipina.

Re : Nitschkia
Hi Alain
I am sorry I dod not keep the specimen. On my photo it is clear that there are no spines , only black-brown, somewhat protruding cells.
My impression is that the spores of N. collapsa are 1-septate already when inside the living asci. I do not think this here is not mature enough, though the spores might change in an overmature stage.
