What is the name of Lovecraft's 36-sonnet cycle published in 1943?

Lovecraft’s 36-sonnet cycle published in 1943 is called “Fungi from Yuggoth.”

Most of the sonnets were written in a burst of activity between December 27, 1929, and January 4, 1930. The sequence moves through visions of forbidden books, strange cities, alien landscapes, occult beings, and cosmic forces, combining poetry with the dreamlike atmosphere associated with Lovecraft’s fiction.

The work is often called a cycle, but its narrative unity is debated. The opening three sonnets form a more recognizable progression involving esoteric knowledge and access to other realities. Many later poems work as separate vignettes, although recurring images and Mythos references give the collection a cumulative sense of nightmare and alienation.

“Fungi from Yuggoth” was published complete in the Arkham House collection “Beyond the Wall of Sleep” in 1943. That title is therefore a related Lovecraft book, not the name of the sonnet sequence itself.
