Tohumlarns

Tohumlarns are a fictional class of seed‑like organisms described in speculative worldbuilding and folklore. In the imagined ecology, they inhabit temperate forests and are characterized by a small, translucent outer shell and a bioluminescent core that contains algal symbionts. Individual tohumlarns range from 2 to 5 centimeters in diameter when mature and form loose networks through a thin, filamentous matrix that links neighboring individuals.

Life cycle and morphology: Tohumlarns alternate between a dormant, seed‑like stage and an active, wind‑dispersed stage. The mature fruit can detach and drift on air currents, settling onto decaying litter or the bark of trees, where it germinates and reinitiates growth. Their tissues are rich in secondary compounds that deter herbivores and attract certain nocturnal insects that aid in spore or seed dispersal.

Ecology and distribution: In the fictional ecosystem, tohumlarns depend on mycorrhizal networks and moss mats for nutrients. Populations tend to form ephemeral colonies that appear after periods of rainfall and moderate temperatures, with coordinated fruiting events that create visible patches of glow at night.

Cultural role: In lore, tohumlarns are associated with renewal and memory, often depicted as seed spirits that guide forest succession. They are sometimes invoked in poetry and ritual as symbols of resilience and regeneration.

Taxonomy and usage: The term tohumlarns is used within fictional contexts and has no standing in real-world biology.
