Rank Reasons
Gymnopilus punctifolius is known from sites in southeastern Alaska, along coastal British Columbia, East along the Rockies in Yellowstone, Colorado, and Taos, New Mexico. It is inferred to be particularly vulnerable to removal of its substrate, clear cutting with burning or removal of all coarse woody debris, or logging activities that appreciably open the canopy and expose the substrate to sun and wind.
Range Extent Comments
Gymnopilus punctifolius sites range from Southeast Alaska, along coastal British Columbia, East along the Rockies in Yellowstone, Colorado, and Taos, New Mexico. The western range boundary follows the California coast ranges south to Sonoma county. There are no known sites in the Sierras.
Occurrences Comments
Gymnopilus punctifolius is known from around 200 sites including about 166 in Oregon, California, and Washington and about 30 in other parts of the range.
Threat Impact Comments
Threats include timber harvest which could impact the over 80% of sites that are not in national parks on as short as a 30 to 40 year rotation, fire which if it occurs on the historic fire return interval may occur between every 25 to over 300 years depending on the site, and climate change which may increase the fire return interval or dry out the forest at an unknown number of sites. The species is also vulnerable to removal of its substrate, clean cutting with burning or removal of all coarse woody debris, or logging activities that appreciably open the canopy and expose the substrate to sun and wind. It is also vulnerable to alteration of microhabitats and microclimate regimes (stream diversion, road construction, development).
Ecology & Habitat

Habitat

This species usually occurs on large woody debris, such as the underside of logs or in stump cavities in mature and old growth forests (Siegel, 2021).
