Don't be fooled by Borges; he was an expert on fantasy fiction and probably knew Lovecraft well before "There are more things" showed up in
The Book of Sand (1975). But I think Borges was ambivalent towards Howie; I faintly remember him (in a preface? a review? an interview?) comparing Lovecraft to some other horror writer (I forget whom) and claiming that he had Lovecraft's imagination without the flaws of his style. Always an enemy of the "baroque", Borges likely didn't cotton to his purple prose. I know that in his 1967 interview with Richard Burgin he implicitly said that he already knew Lovecraft by then - and he didn't like his stories very much.
Borges certainly neglected Howie at times when attention was expected. I just looked up the index of
The Book of Fantasy (1940) he edited with his friends Adolfo Bioy Casares and Silvina Ocampo, and Howie isn't there. In hindsight that's a remarkable oversight.
Then, after
The Book of Sand, Borges also failed to edit a Lovecraft volume for his collection of fantasy,
"La Biblioteca de Babel" (1983-1987): titles by Jack London, Machen, Chesterton, Meyrink (!), Dunsany, but, again, no Howie.
Actually, you made me investigate this matter further, and obviously someone on the net already wrote all about this:

As I expected, Borges was mostly appalled at the style:
"This fact is confirmed by Paul Theroux, who in a 1978 conversation with Borges “about horror stories in general” elicited the perverse revelation that “I like Lovecraft’s horror stories. His plots are very good, but his style is atrocious. I once dedicated a story to him.”5 Ultimately, Borges’s attitude toward Lovecraft can only be described in terms of a syndrome of attraction-repulsion, an aesthetic of extreme polarities or a metaphysics of paradox, similar to the Mysterium tremendum as described by Rudolf Otto.6 Both horns of this dilemma demand their own special polishing."
Crikey!
Rudolf Otto! Syndrome of attraction-repulsion! The Mysterium tremendum! Everything with Borges always has to be so ****ing highbrow and erudite
It's a neat essay, but in 30 pages this dude fails to mention that since the 1920s Borges absolutely loathed purple prose. It's a simple matter of reading his earliest book reviews for
Ultra, El Hogar and
Sur. Borges was in Spain in 1927 when young Spanish poets were rescuing Góngora from oblivion, after 300 years of him being dismissed as a mediocre poet by the Academy - and Borges sided with the Academy's opinion! Borges, like so many Spaniards and Latin Americans the time, believed that Spanish-language writers were afflicted by the "baroque" disease: too much attention to style, too much empty verbosity, obscurity masking lack of ideas, a scourge associated with the 17th century style. Wanting to be modern (not to mention highly influenced by French and English literatures), Borges as a contrarian favored the simple, straightforward, clear style of the likes of R. L. Stevenson, Wells or Machen. Of course a writer keener on displaying ideas transparently would be repelled by Howie's lovely purple prose. There's no big enigma, no recondite explanation. It's as if it's shocking a writer happens to think one of his peers sucks at style.
