beech --- classical semi-diffuse porous; pores are tiny down to uncountable, growth ring boundaries clear due to both a thinning of the pores and a darkening of the tissue at the end of the latewood, plentiful rays of various sizes with the largest ones sometimes visible to the naked eye. Beech is noted for having widely varying ray widths, from very thin to quite thick within the same piece.

Of the semi-ring porous and semi-diffuse porous woods that are otherwise all on the "semi ring porous" page, this one is broken out simply because I happen to have a lot of samples of it.



     
     
     
     
     
 
     
   
these two are from nearby areas of the same piece and are shown together to emphasize the extreme variability of ray sizes within the same piece of beech
   

   

     
spalted beech --- white rot / punkiness makes the end grain characteristics hard to discern
