anidras

Anidras are a fictional group of bioluminescent, fungi-like organisms described in fantasy literature and speculative biology. They are typically small, saprotrophic bodies forming cup- or disc-shaped fruiting structures 0.5 to 2 centimeters across, with a soft green or blue glow visible in darkness. They reproduce by spores released from filamentous tissue within the fruiting body when conditions are moist.

Ecology and habitat: Anidras colonize decaying wood and leaf litter in cool, damp forests. They contribute to nutrient cycling as saprotrophs; some depictions show associations with mosses or algae that share their luminous microhabitat. In many worlds they are rare and patchily distributed, often confined to shaded understories and fallen logs.

Taxonomy and species: In speculative taxonomy, anidras are placed in a fictional phylum Anidromycota, with species such as Anidra luminis, Anidra chloris, and Anidra nocturna. Descriptions vary by author, particularly in luminescence intensity and spore morphology.

Cultural context: Anidras are commonly used in world-building guides as indicators of forest health or as aesthetic luminaries in lore and games. They appear in alchemical recipes or as plot devices involving glow and decay, serving as motifs for nocturnal ecosystems and the interplay of light and shadow.
