Although not formalised and acknowledged as a mythos per se, Lovecraft did correspond with contemporary writers ( Clark Ashton Smith, Robert E. Howard, Robert Bloch, Frank Belknap Long, Henry Kuttner, and Fritz Lieber – a group referred to as the " Lovecraft Circle ") – and shared story elements: Robert E. Howard's character Friedrich Von Junzt reads Lovecraft's Necronomicon in the short story " The Children of the Night " ( 1931 ), and in turn Lovecraft mentions Howard's Unaussprechlichen Kulten in the stories " Out of the Aeons " ( 1935 ) and " The Shadow Out of Time " ( 1936 ).

Derleth expanded the boundaries of the Mythos by including any passing reference to another author's story elements by Lovecraft as part of the genre: just as Lovecraft made passing reference to Clark Ashton Smith's Book of Eibon, Derleth in turn added Smith's Ubbo-Sathla to the Mythos.

With studied playfulness, Smith and Lovecraft borrowed each other's coinages of place names and the names of strange gods for their stories, though so different is Smith's treatment of the Lovecraft theme that it has been dubbed the ' Clark Ashton Smythos '.

Clark Ashton Smith was the third member of the great triumvirate of Weird Tales, with Lovecraft and Robert E. Howard.
