Neoalbatrellus caeruleoporus

Phillips' (1991) concept of Albatrellus caeruleoporus refers to northeastern material. Species Fungorum (2018) transfers Albatrellus caeruleoporus to Neoalbatrellus caeruleoporus.

Total estimated number of occurrences is ~40-60. A North American endemic that is uncommon in eastern North America and with only 10 known occurrences (including BC) rare in western North America. There are 5-8 currently protected occurrences in the northern spotted owl region of the United States. Fungal surveys have not been conducted in all forests so additional occurrences are antcipated. The species is mycorrhizal and dependent upon health and preservation of associated host trees (Tsuga and possibly other Pinaceae) which are valuable timber targets. Cultural characteristics and sexuality unknown.

North American endemic with disjunct populations: northeastern North America (ON, NB, VT, NY, NJ, PA, MI) and western North America, all west of the Cascade crest in BC, WA, OR, CA.

Presumably endemic to North America where it has been collected from 8 states and 3 provinces. Found in northeast North America from Vermont to Michigan and in northwest North America from BC, to CA, where it is considered rare. A total of ~33 collections cited in BPI, NY State Museum databases; Other collections held in WTU, OSC, and MICH also confirmed (Norvell 1995, Ginns 1994). Japanese reports represent A. fletti. There are nine occurrences in northern spotted owl region (Norvell 1995, Castellano 1999, ISMS database 2002) include 2 (CA), 3 (OR), and 4 (WA).

Threats to eastern occurrences are unknown. In western North America,it is possibly threatened by development, hot fires, and forest clearcutting or heavy thinning (probably not by low thinning).
