yellow Ascomycete

Hi,

Last Saturday I found this little yellow Ascomycete on Pyrenomycete. The spores are similar to Ombrophila but orange color I haven't found anything.

The sporal measures are 4-6.1 x 2-2.4 with two guttules.

I am very greatful for any help.

Re : yellow Ascomycete

Could you please give more details on the origin of this fungus? I mean what is the plant on which the pyreno grew, and what is the locality, I mean especially the altitude?

Re : yellow Ascomycete

Hi,

The pyrene was on cut logs of Fagus sylvatica, next to a small river called Basabe, in the municipality of Lizartza at 226 m altitude. lat 43.0856935692, long -2.0018050075

It is a very wet area and has been raining for several days.

Best regards.

Re : yellow Ascomycete

Thanks! I first thought this must be a subalpine species on Alnus alnobetula, but I see I have also samples from lowland in my folder.

Here is a collection studied by Joseba: http://www.ascofrance.fr/search_forum/45995

It usually occurs on Alnus but this one is said to be Quercus.

Another lowland sample is from England made in 2015.

Images you find in Pezizellaceae, Calycina yellow, "alni-viridis"

Re : yellow Ascomycete

Hi,

Perhaps my fungus it isn't mature still that's why the spores are small.

Thanks Zotto for your answer.

Best wishes.

Re : yellow Ascomycete

Ah, you found smaller spores? I overlooked that. Do you have your pics in larger resolution? Then I could better estimate.
