Hello,

In the Netherlands ik found this one on the side of a dry creek.
The size is about 1 cm. The trees around are picea, acer, quercus and alnus.
The hymenuim is yellow.

I don't think he's ripe yet. I don't know if the spores are ripe enough yet.
Spores: 11-14 mu without ornamentation.

In which direction should i llook ?

Regards,
Ronald Morsink

Re : Genea, ?

Dear Nicolas Van Vooren,

I further examined the species microscopically and these are my findings. I used the book: FUNGHI IPOGEI D 'EUROPE.

I measured the asci: 130 µm - 180 µm long and 40 - 60 µm wide.
The spores are : 15-18 µm with ornamentation.
Ornamentation itself : 1 - 1,5 µm
The spores are arranged in the asci
The trees around are: Picea, quercus, fagus, acer and alnus.
The fruitbody: 1-1,5 cm.

I found another fruiting body and I think you can see the yellow between the warts here.

I think it could be Pachyphloeus citrinus.
