Crust Fungus

From back in January: a white crust fungus with a pink pore surface.  It was growing on a branch that had fallen from a deciduous tree.  To give an idea of the scale, the branch was only 4 or 5cm thick.

I used to think it was probably Gloeoporus dichrous but then suspected it might be Junghuhnia nitida.  However, Peter 'Ditiola' at WildAboutBritain thinks it 'looks good' for G. dichrous.  I am keeping a lookout for a further specimen to test this identification using my microscope.  Actually, it was my inability to identify this fungus back in February that finally persuaded me that I needed to get a microscope.
