Tapinella panuoides, also known as oyster rollrim,[1] and as fan pax from its former binomial Paxillus panuoides, is a fungus species in the genus Tapinella.
Atromentin is a phenolic compound. The first enzymes in its biosynthesis have been characterised in T. panuoides.[2]
Despite its pleasant taste, the species is poisonous.[3] In North America it can be confused with poisonous western jack o'lanterns, edible chanterelle mushrooms, false chanterelles (Hygrophoropsis aurantiaca), Crepidotus, or Phyllotopsis.[4]
It grows on wood or in "lignin-rich humus," has little or no stalk where it emerges from the substrate, and the gills appear to be crimped, forked, or crosshatched close to the base.[4]
