Assessment Notes

Justification

Albatrellus confluens is an edible ectomycorrhizal fungus associated with conifers, widespread in Europe but also present in North America. There is no evidence of decline. It can be locally abundant where suitable forest habitat exists. Therefore, it is assessed as Least Concern (LC).

---

Geographic range

Albatrellus confluens is rather common and widely distributed in Europe. It is also present, but less common, in North America. The area of occupancy (AOO) of this species is much larger than 2,000 km², and its extent of occurrence (EOO) is much larger than 20,000 km².

---

Population and Trends

The population size is likely to be very large since this is such a widespread species, and more or less stable as there is no indication of any decline.

Population Trend: stable

---

Habitat and Ecology

Albatrellus confluens is a terrestrial ectomycorrhizal polypore fungus. It grows preferentially in older conifers and form ectomycorrhiza with conifers (e.g. Pinus sylvestris and Picea abies).

---

Threats

There are no major threats to this species. It is commonly and widely found in conifer woodlands.

---

Conservation Actions

No conservation measures are needed for this species since it is widespread and there are no major threats to it.

---

Use and Trade

Albatrellus confluens is an edible species. Sporocarps should be picked young as it becomes bitter and unappetizing as old. Albatrellus confluens contain grifolin, a potential antitumor natural product (Luo et al. 2011).
