I found these on the remnants of leaves of Cirsium or something like that.
They are 0,2 to 0,6 mm wide.

Spores are ellipsoid about 8-12x2-3 and can have some droplets.
Asci are about 40-55x5-6 and paraphyses have swollen tops (2-3 micrometers wide).
Orbilia came to my mind, but the microscophy was too big for Orbilia cardui.

Hi Marja
I suspect this is Rodwayella citrinula. Could you please have a look again and try a preparation of living asci and paraphyses? The latter should contain many droplets (VBs).
Seppo thought on a meeting in Denmark where we had this species, I remember, that he never saw it in Finland, and that it might be more suthern. :-)

Re:On Cirsium
Hi Zotto,
why on earth didn't Rodwayella citrinula come to my mind. Seppo may not have seen them, but I have and several times, usually on grasses, but even on my own yard on Rudbeckia, too. So I should know, that it can grow "anywhere" ;)
I live many hundreds kilometers norht from where Seppo lives, so R. citriniula is certainly not a southern species. It is claimed to be rare in Finland. I have some doubts about that, but I'm surely the only person in Finland to feel so.
These just were too perfict to bring R. citrinula to my mind. They look sometimes like malformed pancakes.
I'll still check the paraphyses with 100x magnification.
Greetings from Marja near Russian border :)

Re:On Cirsium
Oh yes,
Rodwayella citrinula it is. Now I saw the bent paraphyses containing droplets well enough to be confirmed :D
The first one was too badly eaten...
Thank you Zotto.
This was the first finding of this fungus this year. I wellcome it to this years acquaintances and am looking forward to meet again.
Strange how much you can forget during the winter (even if there is a question, has the summer arrived yet, especially after todays hailstorm). Every years first meeting with species seems to be new to you, even if you met them hundreds of times before (though this only 5-10).

Re:On Cirsium
Thanks Marja for your precicions. For me the fungus is actually a rarity, and I am surprized that you are quite familiar to it. i sometimes thoght it is typical on Poaceae but I know it occurs also on dicot herbs.
