Hi Thomas

Tystrup lake, I remember :-)

Damned, I wrote half a roman and after saving I lost it :-(

I wonder why in denmark to my knowledge no O. aristata was found so far.

But the spore head is too long in your sample, it could be O. clavuliaristata but that has shorter tails, or O. clavuliformis which has broader tails, also distinct teeth at the margin.

Best fit some samples we have as "O. cf. aristata" on our O. aristata drawing plate: Figs 10-12.

Presumably they differ genetically from typical O. aristata though we have no proof for that.

I assume you have only very few apos. I wonder if there are very short glassy processes at the margin.

Zotto

one apo only - I looked in vain for more - I saw no marginal protuberances :-(

You saw some? And no photo? How many arms?

Re : Orbila on Cryptomeria; long tailed spores -Jan .2020 Denmark
there are five Danish collections down as aristata plus this new one

https://svampe.databasen.org/observations/495617 (dentate, no ill.)
and the rest likewise older records not illustrated on the databse. Mostly identified as occulta and all s.l.?

Big cross would be wonderful. So this weill remain O. cf. aristata.

This was a thin corticated twig?

For the other I cannot say. O. occulta is so far purely American.
