Here are two speculative anthologies -- maybe not brand spanking new but good markets nonetheless.
Anomalous Appetites: Editor John Irvine hopes to make this the first in an annual series of speculative poetry anthologies. Submit 5-10 short poems by email (artists needed, also) before December 7th. There is a whole message board set up for the anthology here, but you can also find the complete guidelines at HorrorScope. Pays $10 per poet.
Malpractice: The fine folks who bring you Necrotic Tissue are looking for submissions to their hospital horror anthology, Malpractice: An Anthology of Bedside Terror. All submissions must relate to the hospital described in the guidelines, Bloom Memorial Hospital. More information is available in this forum thread. The editors are looking for stories 2000 to 4000 words in length (and also 100 word drabbles). Pay is 1 cent per word plus a contributor's copy. The submission deadline is September 30th or until filled.
Speaking of anthologies, Niteblade's 1-year anniversary anthology, Lost Innocence, will be coming out soon, and editor Rhonda Parrish is holding an online contest to promote it. Winner gets a free copy of the book, which from the line-up looks to be pretty good.
