Preheat your oven to 375°F.
In a mixing bowl, combine the cream cheese, crab meat, green onions, Parmesan cheese, garlic powder, lemon juice, salt, and pepper. Mix until well blended.
Carefully stuff each morel mushroom cap with the crab mixture, pressing gently to fill them completely.
In a separate bowl, mix the breadcrumbs with olive oil until evenly coated.
Place the stuffed mushrooms on a baking sheet lined with parchment paper. Sprinkle the breadcrumb mixture evenly over the stuffed mushrooms.
Bake in the preheated oven for 20-25 minutes, or until the mushrooms are tender and the tops are golden brown.
Remove from the oven and let cool for a few minutes before serving.
