I ran across this call at Hell Notes. The anthology is called "Bride of the Golem" and the editor is looking for humorous Jewish horror stories. You can find all the details, along with an interview with the editor, at http://hellnotes.com/bride-of-the-golem-market-report
One thing you should note is that while the payment is stated as $500 per story, there is no publisher attached to this anthology yet. I've been involved in anthologies that start out with good intentions but if there is no publisher it could takes many years for anything to come of this. So if you have a story, you'll need to have a great deal of patience before this gets off the ground.
