Name: WRJ 0103 Collection Date: 01-03-2026
Fairhope , Baldwin County, Alabama, United States Fungus Type: Gills
Identification(s):
  1. Mycena corticola
  2. Agaricus corticola
Description
On Maple tree front yard. First batch collected when wet. Agaricus corticola vs Mycena corticola: Google AI There's no real "vs" because Agaricus corticola is an older, synonym name for the fungus now known as Mycena corticola, a tiny, delicate mushroom growing on tree bark, characterized by its purplish-brown color that fades and fine granules, known as the Bark Mycena. Mycena corticola (formerly Agaricus corticola) is known for its ability to shrivel in dry weather and re-hydrate later, typical of some Mycena species, and is identified by its white spore print and pleated cap
