Soak oyster mushrooms in 1 cup boiling water for 10 minutes. Strain, reserving liquid. Remove any hard stem ends from mushrooms.

In slow cooker, combine soaked mushrooms, onion, garlic, thyme, salt, pepper and cloves. Add beef. Stir in broth, wine and reserved mushroom soaking liquid. Cover and cook on low until beef is tender, about 8 hours.

Transfer beef to cutting board; cover and keep warm for about 15 minutes before slicing across the grain.

Meanwhile, skim any fat from liquid in slow cooker. Stir in white mushrooms. In small bowl, whisk flour with 1/2 cup water; stir in mustard. Whisk into slow cooker; cook, covered, on high until thickened, about 20 minutes. Stir in parsley. Serve with beef.
