What is panellus stipticus?

Panellus stipticus, also known as the bitter oyster or luminescent panellus, is a species of fungus in the family Mycenaceae. It is a wood-rotting fungus that is commonly found on dead or decaying hardwood logs and stumps in North America and Europe.

One of the most distinctive features of Panellus stipticus is its bioluminescent properties. The fungus emits a greenish light in the dark, making it easily recognizable in nighttime forest settings. This bioluminescence is thought to attract insects that help disperse the fungus's spores.

Panellus stipticus has a shelf-like fruiting body that is beige to orangish-brown in color, with a smooth or slightly hairy cap surface. The gills underneath are crowded and narrow, and may have a pinkish hue.

While Panellus stipticus is not considered edible due to its bitter taste, it is not toxic to humans or animals. It is primarily valued for its beauty and unique bioluminescent properties, and is often sought after by mushroom enthusiasts and collectors for its aesthetic appeal.

In addition to its bioluminescence, Panellus stipticus has been studied for its medicinal properties. Extracts from the fungus have shown potential as antioxidants, anti-inflammatory agents, and antimicrobial compounds, making it a subject of interest for pharmaceutical research.

Overall, Panellus stipticus is a fascinating and visually striking fungus that can be found in woodlands and forests around the world. Its bioluminescence and potential medicinal properties make it a unique and valuable species in the fungal kingdom.
