Assessment Notes

Justification

Ramaria rubripermanens is a common species in western North America. The species is widespread in young to mature forests, and no decline has been noted. It is assessed as Least Concern (LC).

Taxonomic notes

This species was described from a type collection made in Washington, USA (Marr and Stuntz 1973). Field identification of Ramaria is often very difficult, with macromorphological differences being subtle and often intergrading (especially in older fruitbodies). Fall fruiting collections of Ramaria rubripermanens are very similar to R. rubrievanescens, microscopic examination is often necessary for identification.

---

Geographic range

This species is widespread across the Pacific Northwest into northern California in the Coast Range, and Cascade Range into the Sierra Nevada, east into the northern Rocky Mountains. It has also been reported from Quebec, Canada.

---

Population and Trends

The population is very widespread, and locally this can be an abundant species. It is currently known from more than 250 records from around 125 locations, mostly from Oregon, USA. The population appears stable, as no decline has been recorded.

Population Trend: stable

Habitat and Ecology

Fruitbodies are solitary or in scattered troops, growing from soil; fruiting in late spring and fall. It is an ectomycorrhizal species; in California, it is primarily known from, but not restricted to, old-growth forests of Douglas-fir (Pseudotsuga menziesii). In the Pacific Northwest, it is often found with other conifers, especially true firs (Abies sp.), and is common in mid-late seral stage forests.

Threats

Because of the wide distribution of this fungus, and its ability to occur in mid- to late-secession forests, the population overall is presumed to be stable. Locally, climate change and droughts, along with forest management practices has made western forests highly susceptible to stand-replacing forest fires. Fire is a threat to this species. A stand-replacing fire could severely degrade and/or diminish its current range.

---

Conservation Actions

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. 1999). No specific research is needed with regards to this species.

Use and Trade

This species is edible, but only rarely collected for food.
