Mycofiltra gigas
◈ Mycelia Prime — Super-Earth, Hyper-Organic
A colonial bio-organism that harvests atmospheric particulates via piezoelectric digestion, drifting on thermal currents.
Overview
On Mycelia Prime, the atmosphere acts as a dense fluid medium. The Mycofiltra gigas is not a single entity but a macro-colony of trillions of interdependent cells forming a cohesive, buoyant super-organism. It does not rely on passive filtration; it actively pumps air through its porous silicate-reinforced epidermis using ciliary muscles. Buoyancy is maintained not by water regulation alone, but by metabolic hydrogen vacuoles produced during anaerobic digestion of ingested aerosols. The creature grows by accreting new cellular layers, shedding old silicate crusts as it ages. It drifts freely through the mid-canopy, only descending to the fungal bedrock to release reproductive spores, where a temporary anchoring root forms before detaching. Its 'skeleton' is a living lattice of calcified organic fibers that remodels itself in response to stress, ensuring structural integrity against 1.8g gravity and high-velocity winds.
Evolution
Ancestral sessile mats evolved motility to escape ground-level toxins. Genetic mutations allowed for the development of internal gas-production organelles, enabling neutral buoyancy. Over time, the colony structure became more integrated, allowing coordinated movement and complex digestion of atmospheric particulates.
Anatomy
Metabolic Hydrogen Vacuoles (buoyancy control); Silicate-Organic Epidermis (protective, porous); Ciliary Pump Muscles (active airflow); Digestive Vacuoles (aerosol breakdown); Reproductive Peduncle (temporary anchor for spawning); Neural Net (distributed sensory processing).
Behavior
The organism drifts with thermal updrafts, adjusting buoyancy via hydrogen venting or absorption. It feeds by creating localized pressure differentials to draw nutrient-rich air through its body. Reproduction occurs once every decade; the colony descends, grows a temporary root to stabilize against ground currents, releases gametes, then retracts the root and ascends. It communicates via bioluminescent flashes and pressure waves to coordinate swarm migration.
Biology
Metabolism & Energetics: Heterotrophic digestion of atmospheric aerosols combined with piezoelectric energy harvesting from pressure fluctuations; waste is excreted as solid silicate dust.
Sensory Systems: Distributed chemoreceptors and mechanoreceptors embedded in the epidermis detect chemical gradients and pressure changes; no central brain, but a neural net coordinates colony response.
Deep Time & Contingency: Evolved from ground-dwelling filter mats that developed gas-production capabilities to escape toxic surface layers, eventually becoming fully aerial colonists.

Field Notes
- Buoyancy is actively maintained by metabolic hydrogen production, allowing neutral floatation in dense air without rigid gas bladders.
- The 'skin' is a living, growing tissue that incorporates atmospheric silicates into its cell walls for structural reinforcement.
- Energy is derived from the chemical breakdown of organic aerosols and piezoelectric conversion of atmospheric pressure waves.
- Locomotion is achieved through coordinated ciliary pumping and buoyancy adjustment, not passive drifting.
Deep Time
- The Spore AccumulationAtmospheric density increases to 15 atm, creating a permanent fluid-like spore soup.
- The Buoyant ShiftSessile filter-mats evolve metabolic hydrogen production to rise above toxic ground gases.
- The Hydro-Static EraColony structures integrate, allowing coordinated buoyancy control and active feeding.
- The Great FilterMycofiltra gigas evolves, becoming the dominant mid-canopy super-organism.
