Velvet Shank (Flammulina velutipes)
This stump-rotting fungus has attractive orange-brown caps with white gills that turn pale yellow with age. It grows in groups and on upright trees is can form huge tiers. Cultures of Flammulina velutipes were flown on the Space Shuttle Columbia in 1993 to research the reaction of fungi to low gravity. It appears throughout the winter often surviving very cold weather.
