One of the characteristics of the genus Hymenochaete is the existence of prominent setae in the himenium. I take some pictures from the microscope illustrating this feature and I already uploaded a set of photos. According my field guide and taking into account the other features it must be H. rubiginosa. I also saw a description of this species in Roger Mushrooms and I believe that my specimen belongs to it. Moreover, the habitat seems to be the correct one for this species, since tha place where the observation took place is characterized by the existence of very old trees, particularly oaks. I attach a photo of one of old oak living there.

Thanks, Andreas and myxomop, for your opinions.

At first I think this is a species of the genus Amylostereum but now I believe this is a Hymenochaete species.
