Re : Orbilia
Yes! Did they grow together? What substrate?
Patrice TANCHAUD, 14-03-2019 18:17
Re : Orbilia
Yes zotto, they grow together, they were 10 cm apart from each other on Quercus.

Re : Orbilia
Was the hyaline population more sheltered on the underside? Was it a log lying on the ground, with the yellow ones on the lateral side?

Re : Orbilia
Hyaline population sheltered on the underside, yes. It is a log lying on the ground. But for the yellow ones on the lateral side, I do not remember.

Re : Orbilia
It is great that you made so good and many spore photos in close arrangement, this is not easy.

I have three xanthostigma samples of yours for your area, and I see that Nicolas collected leucostigma in Foret d'Aulnay. Anyway, tell me please the locality and date.

Re : Orbilia
I stuck the spore pictures next to each other and cleaned.
