Thoroughly combine the eggs with the ginger, chives, mushrooms, sesame oil, soy sauce, nori shreds, salt and pepper in a bowl. Place 1 scallop in the bottom of 8 small teacups and divide the egg mixture among the teacups. Tap the teacups lightly on the counter to remove any air bubbles. Fill a wok halfway with water and bring to a simmer over high heat. Place the teacups in a bamboo steamer, cover the teacups with plastic wrap and put the steamer into the wok, making sure the base does not touch the water. Steam for 8 to 12 minutes. Remove from the steamer and let rest for 3 minutes before removing the plastic wrap. Check that the egg is cooked by putting a toothpick through the center - it should come out clean. Spoon 1/2 teaspoon of salmon roe onto each steamed egg, sprinkle with chopped chives and serve.
