Frosty webcap

Cortinarius hemitrichus

A species of Cortinar

The gill surface is covered with a partial veil formed by a web of thin fibers when the mushrooms are immature. These mushrooms are inedible, and some similar-looking members of the genus produce a toxin that can destroy the kidneys and liver.
