Rank Reasons
Ramaria aurantiisiccescens occurs in the Pacific Northwest from British Columbia south to California but also in Idaho and Colorado. This is a mycorrhizal mushroom associated with late successional forest. Populations are susceptible to logging including tree removal and compaction. There are potentially 52 known occurrences.
Range Extent Comments
Ramaria aurantiisiccescens occurs in the Cascade and Coast ranges from southern British Columbia to Humboldt County, California. There are also sites is Bonner County, Idaho (collected in 1998 by T. Odell) and Clear Creek County, Colorado (collected in 2010 by M. Wallis and M. W. Beug).
Occurrences Comments
There are 45 to 52 known occurrences, which could be variable depending on how they are delineated.
Threat Impact Comments
Approximately 93% of sites are not in permanently protected areas. If those sites are logged on a 40 year rotation, around 23% would be impacted over 10 years and around 93% would be impacted over 100 years.
