Nitschkia, no! It's a lichen
Anna Klos, 10-05-2024 17:40
Good afternoon,

Thursday during an inventory we found this black ascomycetes.
I think on a branch of Corylus, but I'm not 100% sure.
Perhaps it's a Nitschkia, but the shape as well as the size of the spores (11-12 x 7,2) do not match with any species within this genus. 
What can it be?

With kind regards,


Anna

Re : Nitschkia, no! It's a lichen
As you can see, I added a new photo, wich shows a lichen (next to my so called asco). Riet van Oosten told me this possibility, and she was right (as usual), thanks Riet! I was not aware lichen have also asci with spores. That happens when you are always busy with fungi.

With kind regards,

Anna

Re : Nitschkia, no! It's a lichen
Possibly an Amandinea (punctata).

Re : Nitschkia, no! It's a lichen
Thank you Martin,

It is a very common species, as is also the species next to it. I read that this could be physicia tenella, very interesting!

With kind regards,

Anna

Re : Nitschkia, no! It's a lichen
The last photo is Physcia tenella,

but the others, black "ascomycet", a lichen indeed, is not Amandinea punctata, having 1-septate brown ascospores,
I can see hyaline ascospores, Have they septa or not? Paraphyses tips with cup-like pigment?
Better fotos desired! 

Best Franz

Re : Nitschkia, no! It's a lichen
Sorry Franz, I missed your answer!

Unfortunately no better pictures available.
 
I can not see a septum, but are the spores already mature?

With lichen I did not know what is important to look for.

Thank you for the correction.

With kind regard, 

Anna
