Pleated inkcap, Fan-shaped inkcap, Folded cap
Parasola plicatilis is a species of mushroom in the family Psathyrellaceae. It is commonly known as the pleated inkcap due to its distinctive cap which is pleated when young and flattens out as it matures. The gills of the mushroom dissolve into black ink-like liquid when it is ready to disperse its spores.
Cap diameter ranges from 1-4 cm (0.4-1.6 inches)
Pleated inkcaps grow best in partial to full shade.

The pleated inkcap is a bioluminescent mushroom, meaning it emits a faint greenish glow in the dark. This glow is caused by a chemical reaction between the mushroom and oxygen, and is thought to attract insects to aid in spore dispersal.
