Early life
Born on July 17, 1859, in
Florence, Kentucky, Curtis Gates Lloyd was the third son of Nelson Marvin and Sophia Webster Lloyd. He and his family moved to
Crittenden, Kentucky
Crittenden is a home rule-class city in Grant and Kenton counties, Kentucky, in the United States. The population was 4,023 as of the 2020 Census, up from 3,815 as of the 2010 census, which was further up from 2,401 at the 2000 census.

and was employed as an apprentice in Johnson's pharmacy. This was where he met Dr. John King, physician and editor of the ''American Dispensatory''; the close friendship they formed helped to fuel Lloyd's interest in botany.
Lloyd earned his pharmacy certificate while working at the pharmacy. Later, Lloyd was a salesman with Hale, Justice and Co., a drug supply company, and he began accumulating a personal collection of flowering plants.
Career
Lloyd, together with his brother
John Uri Lloyd, started publishing ''Drugs and Medicines of North America'', a quarterly publication that became popular in the fields of

was initiated after a meeting with
Andrew Price Morgan in 1887. Soon after, Lloyd directed his attention to the study of the
Gasteromycetes, taking field trips and forays to various exotic locales, and collecting more specimens for his growing personal herbarium. In the early 1900s, Lloyd established offices in both

. He began publishing his mycological findings, and quickly gained a reputation for his views on the use of personal names in the identification of fungi.
He became well known for publishing tirades against the convention of citing author's names after the
generic name and specific epithet of plants and fungi, a practice he called "species-grinding". Because he published privately, Lloyd was free to criticize other mycologists guilty of hastily publishing new species. In the article "The Myths of Mycology" (1917) he wrote,
... the mistakes, blunders, and personal foibles of mycological writers have been my chief source of pleasure. I have never failed to express myself plainly, and have spared neither friend nor antagonist. I have always tried to be good-natured in my comments, and as a general thing the parties affected are taking it more as a joke on themselves and an idiosyncrasy of myself. ... Nor am I deceiving myself into the belief that I will accomplish what I am trying to bring about, the abolition of personal advertisements in mycology.
His conservative approach to classification was later criticized by
Marinus Anton Donk
Marinus Anton Donk (14 August 1908 – 2 September 1972) was a Dutch mycology, mycologist. He specialized in the Taxonomy (biology), taxonomy and nomenclature of mushrooms. Rolf Singer wrote in his obituary that he was "one of the most outstandin ...
, who wrote "The terror that Lloyd spread among North American mycologists and abroad by ridiculing everything that reminded him of taxonomic innovation in the systematics of fungi ... has not yet been completely overcome. His slipshod taxonomic methods were accepted as standard by some of his correspondents."
Lloyd spent much of the latter half of his career working on the
polypore fungi, of which he amassed an extensive collection later described by
Josiah L. Lowe as "undoubtedly the best single source of information on the species of the world."
In 1926, plagued by failing eyesight, Lloyd was forced to retire from his mycological work, and returned to Crittenden, where he lived until his death from complications of

endowment with the
Lloyd Library and Museum.
In accordance with his wishes, Lloyd's body was cremated, and his ashes spread on his property in Crittenden. However, he constructed a gravestone for himself before he died, which was also placed on the property, with a double-sided, unusual epitaph:
Front side:
Curtis G. Lloyd: Monument erected in 1922 by Himself, for himself, during his Life, to satisfy his own vanity. What fools these mortals be!
Rear side:

He published 26 issues of ''The Bulletin of the Lloyd Library''; six of these were written by him on mycological subjects. He also published 75 issues of ''Mycological Notes'' over a period of 28 years (1898–1925).
