Hello,I have trouble distinguishing above mention

Rutstroemia/Ciboria or what?

Elsa Sousa, 21-12-2020 21:06

Good evening,

I saw this fungus on wood debris. I'm not sure about the wood, there are many trees nearby, mostly oaks, but spruce too, though it doesn't seem a stick from spruce to me.

Spores measure +/-: (11.9) 12.2 - 14 (14.2) × (3.7) 4.5 - 5.2 (5.3) µm

Would you please help me?

Thank you

Elsa

Re : Rutstroemia/Ciboria or what?

This requires at first the excipulum, globulosa or prismatica? Best is a photo.

How are the living paraphyses?

Host loooks like oak.

Re : Rutstroemia/Ciboria or what?

Hi Zotto,

Hyphal structure is prismatic as seen in photo IMGP0375 (2).JPG a bit gelatinized. About paraphyses, I don't know how to describe... I'm not sure but I think I didn't see any septa, some granules here and there only.

Thanks

Re : Rutstroemia/Ciboria or what?

Paraphyses are always septate, but important is if there are refractive vacuoles in them when alive.

Not sure if the photo shows the ectal excipulum.

Sorry, this is too unclear to me.

Elsa Sousa, 21-12-2020 23:39

Re : Rutstroemia/Ciboria or what?

Sorry Hans, paraphyses looked boring to me, nothing invulgar, not vacuoles or if so, very few, few septa and the apices a bit rough. I have seen no globular texture in all of the specimen.

This asco is different, is that important? (Photo)

Whatever, does this remind you any genera (looking at the spores, it appears they would have a septum I saw one inside the ascus with it. Would you give me some names to look for?

Maybe a immature Rutstroemia firma, what do you think?
My photos are poor, but this ones remind me my fungus: http://www.ascofrance.fr/forum/26392/rutstroemia

Re : Rutstroemia/Ciboria or what?

Your fungus has mature spores which are much smaller than in Rutstroemia firma and similar species, with two diecrete large LBs and no smaller one saround them. This does not fit any of the Rutstroemias that I know.

The last pic shows an immature ascus with vacuoles.

I am sorry I have no idea of a genus, only Rutstroemiaceae seems certain. It would be great if this is a Lanzia, but the images I have of that difficult genus do not fit either.
