Pleurotus ostreatus
pleurotus ostreatusAlso known as Grey Oyster Mushroom, Oyster Fungus, Hiratake, Pearl Oyster Mushroom
Oyster mushrooms grow in shelf-like clusters on decaying hardwood trees, displaying broad, fan-shaped caps that range from cream to dark grey. These fungi play a vital role in forest ecosystems by breaking down lignin and cellulose, effectively recycling dead wood back into the soil. They are also carnivorous, using specialized mycelial hyphae to paralyze and consume microscopic nematodes for nitrogen.

Many edible mushrooms have toxic look-alikes; never eat wild fungi based on app identification alone.
- Check the gills: Look for gills that run down the stem, a key feature known as decurrent gills.
- Smell the cap: Fresh specimens often emit a faint, sweet aroma reminiscent of anise or licorice.
- Examine the wood: Search for these shelf-like clusters on dead or dying hardwood trunks, especially after autumn rains.
