Preheat the oven to 375°F. Line a baking sheet with parchment paper or a silicone baking mat. Wash the morels well, cut in half, and pat dry with paper towels. In a bowl, stir together the egg, mayonnaise, green onion, Worcestershire, and salt, pepper, and hot sauce to taste. Add the crabmeat and ½ cup of the breadcrumbs and stir just to combine. Adjust seasonings to taste.
