'ulalume writer' is the definition.

This is the entire clue.
(Other definitions for poe that I've seen before include "Edgar Allan ..., American writer of the macabre" , "The Raven poet" , "Edgar Allan . . ., American writer of horror stories" , "The Raven writer" , "Edgar Allan ---, poet more famous for his gothic short stories" .)
