Morelull is based off of a Coprinellus disseminatus (also known as a Fairy Cap Mushroom). This also explains its fairy typing.
Morelull may be a combination of morel (a type of edible fungus) and lull (to make someone or something go to sleep). Most of the letters from its name can also be found in the name Coprinellus disseminatus (the mushroom Morelull is based off of).
