Hi everybody, here I attach a document that you can download and share it with everybody. Maybe you are interested in helping us, or you know somebody or you know some mycological society near to the localities that this species has been found it before. Probably is more common that we know in Europe, always growing in old Quercus trees, in dying (or dead) attached branches, but also probably in the detached ones on the ground. Share it! the more people see it the more possibilities to find it.
Best wishes
Luis Quijada
