The Primroses Were Over

I have definitely read the titular "Shoggoths in Bloom", though precisely where I cannot tell you. I remember liking it, I think, though I don't remember the ending, which is always fun. I probably picked it up in one of the dozens of Lovecraftian anthologies I read when I first got into the genre (can we call that a genre? I'm not sure what else to call it).
