Fungi from Yuggoth is a sequence of 36 sonnets by cosmic horror writer H. P. Lovecraft. Most of the sonnets were written between 27 December 1929 – 4 January 1930; thereafter individual sonnets appeared in Weird Tales and other genre magazines. The sequence was published complete in Beyond the Wall of Sleep (Sauk City, WI: Arkham House, 1943, 395–407) and The Ancient Track: The Complete Poetical Works of H. P. Lovecraft (San Francisco, CA: Night Shade Books, 2001, 64–79). Ballantine Books’ mass paperback edition, Fungi From Yuggoth & Other Poems (Random House, New York, 1971) was followed in 1982 by the chapbook printing of Lovecraft's sonnet cycle (Necronomicon Press, West Warwick, RI). This may have been the first time that the sequence was published in its corrected text.
Fungi from Yuggoth represents a marked departure from the mannered poems Lovecraft had been writing up to this point. Sending a copy of "Recapture" (which just predates the sequence but was later incorporated into it) the poet remarks that it is 'illustrative of my efforts to practice what I preach regarding direct and unaffected diction'.
The sonnet forms used by Lovecraft veer between the Petrarchan and the Shakespearean. His multiple use there of feminine rhyme is reminiscent of A.E. Housman (e.g. in sonnets 15, 19). In addition, his sonnet 13 (Hesperia) has much the same theme as Housman's "Into my heart an air that kills" (A Shropshire Lad XL).
Varying opinions have been expressed in the critical literature on Lovecraft as to whether the poems form a continuous cycle which tells a story, or whether each individual sonnet is discrete. Phillip A. Ellis, in his essay "Unity in Diversity: Fungi from Yuggoth as a Unified Setting", discusses this problem and suggests a solution.
