Apokrupka has put out calls for two anthologies. The deadline for both is November 3.
The first is "Vignettes From the End of the World". They want you to tell about that moment when the world ends in 500 words. Payment is $20.
"Fur and Fang" is looking for Horrotica (monster sex). Stories should be 2000 to 4000 words, payment is $50.
Submissions are through their submittable page. I've posted the link because the one for Vignettes isn't on the site yet, but they are open.
Apokrupka has been in business for a year and they are the people behind the horror zine Lamplight.
