Innsmouth Free Press has the guidelines online for the anthology of short fiction titled Fungi…

“Fungi is an anthology of dark speculative fiction (horror, fantasy, science fiction, and any other variant, such as steampunk) focused solely on the fungal.”

Don’t forget that most of the fungi is down below ground, and what we see as toadstools and mushrooms are just the fruiting bodies. I also discuss bio-luminous slime molds at length in my long essay on the sources and wider historical contexts of Lovecraft’s “The Colour out of Space”, to be found in my Lovecraft in Historical Context: Further Essays and Notes (2011).
