Plicariella
Ronald Morsink, 21-10-2021 20:14
These i found on the side of a dry creek in the Netherlands. They grow on the soil. The trees nearby are betula, castenea, alnus and fagus. 

The outside is brownish with warts. The hymenium color is black. 

The spores have one large oil drop. 
Spores size measured in water without ornamentation: 12-14 mu.

Asci : amyloïd
Asci: 270 mu - 340 mu long at 20-22 mu wide. 
The ascitop turn blue with lugol. Also blue with melzers.
8 spores in the asci. 

Could it be Plicariella scabrosa ?

Regards, 
Ronald Morsink

Re : Plicariella
Hi Ronald
I suspect that Rene and Nicolas have adequate knowledge about this species.
I had the pleasure to meet this genre twice. During Identification, I used their work. I suspect that this is probably a species quite a rare and demanding further research.
By examining my collections I could not get a blue reaction to iodine, so only this feature differs our collections. Other features are identical.
Not having too much choice, I also gave him the same name.
I'm not sure if rightly?
If you want, you can compare.

Re : Plicariella
Hello Mirek,
okay, then I'll wait and see if I get a response from them.
You have made a nice collection of it, and indeed other features are identical.

Thank you for your comment.

Hello.
The spore ornamentation points to P. scabrosa, although the spore size seems a bit short...

Re : Plicariella
Dear Nicolas Van Vooren,

Thank you fot the comment. It is possible that te size of the spores is a bit short, I have I measured without ornamentation.
Because several rings can be seen visually, I measured the inner ring, so the spore size would be larger. That might be one reason.
