Nitschkia

Hans-Otto BaralHi all

I 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?

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.
