What You Should Know
Neoalbatrellus caeruleoporus (Albatrellus caeruleoporus) is a nontoxic and inedible mushroom distributed in central and southwestern China. Its fruiting body is white with light blue skin on the pileus.
Its distribution is restricted to the coastal areas of western North America from British Columbia into northern California. Despite medium-sized, charismatic blue sporocarps, it is obviously very rare and only reported a few times. Despite being a Survey and Manage species in the North West Forest Plan and looked for during the last 20 years, the species was never encountered in Oregon and Washington. The suspected population size is estimated to be less than 2000 and the current trend is unknown.
Other names: Blue-Pored Polypore.
