is an ectomycorrhizal ‘tooth fungus’ growing in association with Pinaceae, especially in wet coastal forest with Sitka Spruce (Picea sitchensis
). The population is widespread and stable. It is assessed as Least Concern.
was described from western North America, with the type collection made in northern California, USA (Harrison 1964).
It is known from the Santa Cruz Mountains in California, north into south-east Alaska, in coastal and Coast Range forests.
Population and Trends
The population occurs over a widespread area, and can be locally common to abundant; although more scattered on the southern and northern fringes. Unlike many members of Bankeraceae, it can be found in younger forests. No decline has been noted.
Population Trend: stable
Habitat and Ecology
It is ectomycorrhizal with conifers, especially Sitka Spruce (Picea sitchensis
) in coastal forests. Fruiting is in late summer or early fall, with fruitbodies long-lasting, continuing their growth into winter. Typically it is found in large gregarious patches, and often mixed with other Phellodon
No significant threats have been identified with regards to this species.
This species is included on the United States Forest Service Northwest Forest Plan Survey and Manage list of rare/old growth forest-dependent fungi, and has been actively surveyed for since the late 1990's (Castellano et al.
2003). No specific research is needed with regards to this species.
Use and Trade
is a highly sought-after dye fungus, and has the potential to be overharvested in some locations.
