A Young Amanita smithiana.
Hopefully an educated guess. A. smithiana fruit in September to December and are found in coniferous forests. This specimen was found under a hemlock tree. Another point that limited my options is that A. magnaverrucata is not found in this area.

''Amanita smithiana'', also known as Smith's amanita, is a species of agaric found on soil in coniferous and broadleaved woodland in the Pacific Northwest of North America. It fruits in August and September.
