Aldine Invention (UK 1899–1905) was a British reprint of the US Frank Reade Library (1892–1896), which began with the Steam Man story.
The Idler (UK 1892–1911) was a British literary magazine that published both fantasy and science fiction stories, most notably by: Arthur Conan Doyle, Mark Twain, H. G. Wells, Edwin Lester Arnold, and William Hope Hodgson. The founding editors, Jerome K. Jerome (1859–1911) and Robert Barr (1850–1912), were both genre writers.
Argosy (US 1882–1943), the first regular pulp magazine, published a great deal of fantasy and science fiction until 1943, when editorial policy eliminated those genres. Prior to 1910 Argosy published stories of genre relevance by Upton Sinclair, Frank Aubrey, James Branch Cabell, Howard R. Garis, and George Griffith. In the late teens it began to publish stories by authors who would later help to establish the SF genre as we know it, like Garrett P. Serviss and Murray Leinster.
The Black Cat (US 1895–1919; The Thriller 1919–1923) was more mystery than fantastic, but set the stage for later weird-tale magazines. Published a number of ghost stories, but more widely remembered as the magazine that bought Jack London's early stories.
Pall Mall Magazine (UK 1893–1937; combined with Nash's Magazine in 1914) was the stomping grounds for H. G. Wells in the 1890's, also publishing stories by Algernon Blackwood, and M. R. James. Its influence on the 1900–1920 period was less.
Other magazines in the 1900–1920 period that produced some stories of genre interest were: Blackwood's Magazine (1817–1980), Harper's Monthly (1850–present), Atlantic Monthly (1857–present), The Strand Magazine (UK 1891–1950), and Pearson's Magazine (UK 1896–1939).
