cortina
Definition
Noun: 1. A cobwebby partial veil consisting of silky fibrils: In mycology, a cortina is a delicate, web-like, often temporary membrane of fine silky threads that connects the edge of a mushroom's cap (pileus) to its stem (stipe) in young specimens. It is a type of partial veil that typically ruptures and may disappear as the mushroom matures, sometimes leaving remnants on the stem or cap margin.
Usage Examples

Advanced Usage
- "Cortinal remnants": Refers to the leftover silky threads or fibers on the stem or cap margin after the cortina has ruptured.
- Look for cortinal remnants on the stipe to confirm the identification.
