*Panellus stipticus*

Only eastern North American populations of this fungus emit light; European populations of the identical species are completely non-bioluminescent.

- **Taxonomy:** Fungi › Basidiomycota › Agaricomycetes › Agaricales › Mycenaceae › Panellus
- **IUCN Red List status:** Least Concern
- **Population trend:** stable
- **Biome:** forest
- **Habitat:** Temperate deciduous and mixed forests, growing on rotting logs, fallen branches, and stumps of oak, beech, and birch.
- **Diet:** Saprotrophic, decomposing lignin and cellulose in dead hardwood as a white-rot agent.
- **Range:** North America, Europe, East Asia, Oceania
- **Size:** Cap width 1.2–3.2 cm, stem 0.6–1.2 cm long
- **Lifespan:** 1–3 months (fruiting body)
- **Active:** nocturnal
- **Threats:** Clear-cutting and the systematic removal of coarse woody debris from managed commercial forests.
- **Safe to approach?:** Harmless to touch and safe to observe closely. Do not consume, as it contains strong astringent compounds that act as a violent purgative, causing intense gastrointestinal distress and vomiting if swallowed. Wash hands after handling wild specimens.
