I have always heard it in conjunction with pork. And here is the exact definition

In its traditional Chinese version, moo shu pork (木须肉 / mùxūròu) consists of sliced pork tenderloin, cucumber, and scrambled eggs, stir fried in sesame or peanut oil together with thinly sliced wood ear mushrooms (black fungus) and enokitake mushrooms. The dish is seasoned with minced ginger and garlic, scallions, soy sauce, and rice cooking wine (usually huangjiu).
