Hi! Monday I took my husband out for a birthday lunch at a Chinese buffet, and there on the steam table, labelled "Greek Mussels" was not an "edulis" but a mussel with emerald green periostracum, with brown longitudinal stripes. The only "green" mussel I could find in my books was "viridis," which is not from Greece. (Could the recipe have been Greek?) Does anyone know what I have (of course, I brought the shells home; too bads I couldn't get the matching valves, short of going through their dumpster later that night, and my husband would have said a definite NO to that). Does anyone know what I might have. It does look as if there is one tooth in one valve, and two in the other, but I'm not sure of that. Thanks, Linda Bush
