Hello,

finaly I had time to study this immersed one, that I found a week ago.
Luckily it wasn't spoiled yet. These are 0,5-1mm wide:

The spores are about about 50-85x4-5 , septate and contain small droplets:

Re:On Prunus padus bark
The asci are about 75-95x10. There are loads of narrow (about 2 wide) paraphyses and asci are difficult to see.

This may be a Stictis and I have a link to Mycotaxon side, where they are represented in numerous pages, which have to go through one after another. It would take hours to try to determine with them. So I can only hope, that this species is familiar to someone.

Hi Marja,

on p. 269 in Sherwoods work on Ostropales you will find an host index. Prunus is represented on p. 71 and 182.
Maybe this helps...

Best regards,

Martin

Hi Marja,

I think this could be a Karstenia from the K. idaei-group. Try IKI and you should see a nice reaction of the hymenium.

Best wishes,

Gernot

Re:On Prunus padus bark
Dear Martin,

thank you for the hint of the host index!

Dear Gernot,

I really wish to find species of generas named after our Karsten :)
The spores and asci fits quite well, but I tried IKI and don't remember noticing anything very special.
I got a feeling, that there was something glue-like material on the asci and paraphyses.
I had to push hard just to see any asci.
Maybe the material looks like this:

You are right, Gernot, I think it is K. idaei.

Re:On Prunus padus bark
Oops, two votes for Karstenia idaei.

If this stands, it would mean a new genera for me, a new species for Finland and that my smile will be very wide :)
