Mytilus trossulus?

I stayed in Denmark for a month a while back, I lived in Hillerod but went to a few beaches on the North of Sjaelland around the Hundested area (worth a visit if you go there again!). Not much in the way of shells really, not helped by there being hardly any tide! I did find some interesting Littorinas on the rocks and a few bivalves on the beach. The best place was in the Harbour where the fishing boats wash their nets out, found a pile of Modiolus modiolus mixed in with Cyprina arctica and a few other odds including my first Capulus ungaricus.
Denmark is a beautiful country, I fell in love with it on my first visit for a week in the Summer of 2011. That is when I visited Copenhagen with the friend I was staying with. A beautiful city with spectacular Botanical Gardens and a really nice geological museum. One day I hope to go back there but it does have a few bad memories. Long story!
