Cup Fungi = Pezizaceae is the usual irritating common name nonsense in iNat/NW. There are more cup fungi that aren't pezizaceae than are, and many species in the pezizaceae that are nothing like cup-shaped. Common names for fungal higher taxa don't usually work. They are descriptive of course, but to work they would need to be bound to miscellaneous groups of species with no exclusive common ancestry.
