Large-spored Propolis on Populus tremula

Spores measuring (40-) 43-47 x 10-12 microns. Two large LBs and many small (occasionally one or two intermediate).  Is P. betulae the correct name for this? Or P. versicolor var. betulae?

Found in Central Norway, on aspen.

Thanks.

Re : Large-spored Propolis on Populus tremula
Thanks for your reply.  Yes, and your key took me to P. (versicolor var.) betulae. However, only Quercus and Pinus are mentioned as substrate. P. betulae is not known from Norway, so I wonder if that is a name to be used or whether versicolor var. betulae is more appropriate.
