Burial Day Books has issued a call for submissions to their Gothic Blue Book series. They're looking for Gothic stories around 3500 words long. In the guidelines you'll find a list of acceptable settings for your story. The deadline is July 19, payment is $25. You can find the details here
Burial Day also accepts short stories for their online site but there's no payment for these. The upside is that there are stories available on the site so you can get a feel for what they're looking for.
