Rank Reasons
Endemic to the Pacific Northwest. Known from 16 sites. This speces is often erumpent and easily seen in the low density underbrush forests that it occurs in. There have been several recent new locations in Washington, an area not as well examined for sequestrate species of fungi. I believe there will be many more.

Threat Impact Comments
This is a mycorrizhal species; it is dependent on a host tree for its carbohydrates. Studies have shown that if the tree is killed the mycorrizhal fungi die shorty after. The one possibly saving feature of this species is the spore bank. However, nothing is known about the spore bank of this species.
