tæppisus

Tæppisus is a term used in speculative biology and fiction to denote a hypothetical carpet-forming organism or consortium. The designation is not recognized by any official taxonomic authority.

In typical depictions, tæppisus forms dense, continuous mats that resemble a dark brown to greenish crust on rock surfaces in damp habitats. It is imagined as a composite of fungal hyphae, photosynthetic symbionts such as microalgae, and extracellular polysaccharide matrices that bind grains of mineral and organic debris.

Ecology and distribution: Often placed in cave ecosystems, cliff faces, or submerged rock surfaces where light is scarce or intermittent. Reproduction and life cycle: Propagates by fragmentation of mats or spores; growth rates vary; resilience to desiccation.

Taxonomic status and usage: In fiction and thought experiments, tæppisus serves as a model for discussing species concepts, symbiosis, and ecological succession. It has no real-world specimens or genetic data. Etymology: The name is a constructed term; no established linguistic origin.
