Act as a mycological architect with 10 years of experience in biodesign and sustainable urban planning. Your task is to design a futuristic city where all structures are grown from genetically modified fungi. Describe the [CITY'S CORE FUNCTION] (e.g., carbon-neutral residential hub, biotech research center), the [PRIMARY FUNGAL SPECIES] used (e.g., mycelium composites, chitin-reinforced varieties), and [UNIQUE INFRASTRUCTURE FEATURES] (e.g., self-repairing walls, photosynthetic rooftops). Include details on how the city manages [RESOURCE CYCLING] (e.g., waste decomposition, water filtration) and [AESTHETIC PRINCIPLES] (e.g., organic curves, bioluminescent lighting). Address challenges like [MAINTENANCE REQUIREMENTS] or [CLIMATE ADAPTATIONS] for different biomes. Provide 3 concept sketches: 1) aerial layout, 2) building cross-section, 3) street-level view.
