Björn WergenHello,

I have some problems with these two findings:

The first one is, hopefully my determination is correct, Leucoscypha semi-immersa (micro see photo). Fb size about 2-6 mm, orange-brown.

The second species is perhaps not L. semi-immersa, even if it looks like this in the microscopic features. But have a look on the macrophoto, it shows a completely different ascomata being bigger in size (4-12 mm) and having another color.

Are the showed species two different one or just an example of L. semi-immera variability?

Thanks a lot,
cheers, Kazuya

Hi Kazama,
Are the apos lying on burnt ground ?
I would suggest then Leucoscypha patavina which is also fairly common on sandy soil on the coas.
Amitiés

Michel

Re:Leucoscypha semi-immersa
Hi Michel,

I have also thought about L. patavina, it was even my first thought after I had found this species. I am not sure now, I will proof it tomorrow, but the key did not take me to L. patavina, but to L. semi-immersa, which was already found and determined. This one is NOT L. semi-immersa, I think.

I cannot tell you if it is burnt ground. If yes, it was not obvious, but I am sure the location had something special, perhaps also with some burnt ground.

cheers and thanks,
Kazuya
