Mytilus trossulus?

Mytilus trossulus?
Hello everybody!

In December I was in Copenhagen, Denmark, and on Amager Strand beach, 5 mins from Copenhagen city centre I found the following Mytilus specimens. I have done some research on the internet (I am not a Mytilus expert) and have found out that in the Copenhagen area Mytilus trossulus or a hybrid between Mytilus trossulus and Mytilus edulis is prevalent. I have taken pictures of all the Mytilus specimens I collected and I really need your help to decide whether they are Mytilus trossulus, Mytilus edulis or what the internet calls Mytilus edulis f. trossulus. I think that some of them are clearly (and based on the images I have found on pages like <!-- m --><a class="postlink" href=""> ... -recid=410</a><!-- m -->) are Mytilus trossulus.

Please, can anybody help?

Many thanks!
