Assessment Notes

The content on this page is fetched from The IUCN Red List of Threatened Species: https://www.iucnredlist.org/species/195922088/195926531

Justification

Lactarius xanthogalactus is a very common milk cap, occurring in both conifer and hardwood forests across California and Oregon, USA. The species is widespread, and no decline has been observed. It is listed as Least Concern (LC).

Taxonomic notes

This species was described as Lactarius xanthogalactus, from a collection made at Stanford University (Peck 1907). However, this name was rarely used, and collections of this species were referred to as Lactarius chrysorheus and Lactarius vinaceorufescens (Hesler and Smith 1979, Arora 1986). Research into California Lactarius (Methven 1997) clarified the taxonomic issues.

Geographic range

This species is very common across most of the forested low and mid elevation parts of California and southern Oregon, USA, but is only occasional north through Oregon. It is also found in northern Baja California, Mexico.

Population and Trends

The population is widespread, in many different habitat types. It occurs in both conifer and hardwood forests in coastal and low montane forests across California, with no sign of decline.

Population Trend: stable


Habitat and Ecology

It is ectomycorrhizal with hardwoods, especially oaks (Quercus spp.) and Tanoak (Notholithocarpus densiflorus), and conifers, especially Douglas fir (Pseudotsuga menziesii). It is very common in young to mature forest across California.

Threats

No specific threats have been identified with regards to this species.

Conservation Actions

No specific conservation actions are needed with regards to this species, and no specific research is currently needed either.

Use and Trade

No use/trade is known.
