Described from California, USA (Smith & Thiers 1964). Suillus subacerbus McNabb is a synonym (NZ Fungi Database 2021)
Suillus pungens is a common Suillus native to California, USA, and introduced elsewhere in the world.
Native habitat (Pinus radiata and P. muricata forests) is under threat, but Suillus pungens is highly adaptive, and occurs with a wide range introduced pine species, and with planted and naturalized P. radiata and P. muriata stands in California.
Because of the adaptability of this species, and how common it is across California, it should be listed as Least Concern (LC).
Native to coastal California, USA with Pinus muricata and P. radiata; but widely introduced in California; with both planted and naturalized native pines, and introduced P. pinea, P. pinaster, and P. halapensis (Nguyen et al. 2017). Common with introduced P. radiata in New Zealand, and reported from Australia with introduced pines.
Population is stable and widespread with introduced and naturalized habitats; both in/near the native range in California, USA. Introduced to New Zealand.
Native habitat is under threat; Pinus radiata is listed by the IUCN as Endangered (Farjon 2013-b) and P. muricata as Vulnerable (Farjon 2013-a).
Ectomycorrhizal with Pinus muricata and P. radiata in its native habitat, but widely introduced in California; with both planted native pines, and introduced P. pinea, P. pinaster, and P. halapensis (Nguyen et al. 2017), especially in urban areas. Common with introduced P. radiata in New Zealand.
In native habitat, this species occurs with two pine species under threat; Pinus radiata is listed by the IUCN as Endangered (Farjon 2013-b) and P. muricata as Vulnerable (Farjon 2013-a), mostly due to habitat loss due to urban development and fire regime change. However, Suillus pungens has been highly adaptive, and is quite common with planted and naturalized P. radiata and P. muricata, and with introduced P. pinea, P. pinaster, and P. halapensis in urban areas across much of coastal California.
Protect and manage coastal Pinus muricata and P. radiata forests in California.
No specific research is currently needed in regards to this species.
This species is edible, but rarely collected.
