Phoenix Fire Publishing has four open anthology calls (scroll down the page). All stories should be 800 to 7000 words. Payment is split royalties. And the open calls are:
Blood Games - deadline September 12 - Vampires
Serrated - deadline October 1 - horror
Wicked Enticements - deadline October 8 - erotica
Mystic Moon - deadline November 20 - dark fantasy
One thing bothered me about the guidelines - "editing will be provided unless author prefers their own editor". I've never seen a statement like this in any guidelines. They provide editing services on their site, but don't really say that you have to pay to have your story edited for the anthology. So something to check out if you decide to submit. You can find the details here.
