The species that I did notice were oak, Ash, horse chestnut and sycamore, however there did seem to be a good variety of other species too. We were well up in the Yorkshire Dales but down at river level, it was a logged up tree and couldn't bring myself to pass up the chance with grain like that. The spoon is looking really nice.
The dark wood is very hard on the knife, the edge soon needed retouching, is it common for spalt to be harder than the normal wood?
Once cut, the wood seems to take on a red/pink tinge, perhaps a clue to the species? It smells kinda unpleasant too.
