What is hairy mycena?

Hairy mycena, also known as Mycena setosa, is a species of mushroom found in the forests of North America, Europe, and Asia. Hairy mycena typically appears in autumn and winter, growing in dense clusters on decaying logs, fallen branches, or buried wood. The cap of hairy mycena is small, usually less than 2 cm in diameter, and has a smooth texture with a reddish-brown color. The stem is slender and may be up to 6 cm tall, with a hairy surface that feels rough to the touch. The gills are white and have serrated edges. Hairy mycena is not considered a choice edible mushroom due to its small size and tough texture, but it is sometimes used in folk medicine for its antibiotic and anti-inflammatory properties.
