is a common milk cap in southern and central California, USA, found in oak woodlands. No decline has been observed although localized threats may exist. It is listed as Least Concern (LC).
This species was described from a collection made at Stanford University, California, USA (Peck 1907).
This species is known from California, USA. It occurs from San Diego County north into Sonoma County in coastal and coast range oak woodlands, and around the southern and central portions of the Central Valley in similar habitat. It is likely to also occur in Baja California, Mexico.
Population and Trends
Lactarius rufulus is very common, occurring over a wide area. Much of its habitat is around urban areas, including some subjected to development, but likely not at a scale that would affect the population overall.
Population Trend: stable
Habitat and Ecology
This species is ectomycorrhizal with oaks (Quercus
spp.), especially Coast Live Oak (Quercus agrifolia
). It is more common in hotter, drier oak woodlands (southern California). Fruiting occurs from fall into spring; depending on seasonal rainfall.
Urban development is a potential threat, but not at a scale to affect the population overall. Loss of oak woodlands is an additional threat.
No specific conservation actions are needed with regards to this species, and no specific research is currently needed either.
Use and Trade
This species is edible, and occasionally collected for food.
