Assessment Notes

Justification

Polypus dispansus is a polypore known from North America and Asia. Even though this is species does not appear to be common, it has a wide distribution, a potentially large area of suitable habitat and there is no evidence of population decline. Therefore, it is assessed as Least Concern (LC).


Taxonomic notes

Polypus dispansus is the only species in its genus, created using morphologic and molecular data (Audet, 2010).
Synonyms: Polyporus dispansus, Albatrellus dispansus.


Why suggested for a Global Red List Assessment?


Geographic range

P. dispansus has a wide distribution in North America and parts of Asia. It has been recorded in China (Zheng and Liu 2008), Japan, South Korea, North Korea, Lao Peoples Democratic Republic, India, the United States of America, Mexico (GBIF.org, 2023) and Costa Rica (Audet, 2010).


Population and Trends

P. dispansus has been documented as rare in China (Dai, 2012), but has a wide distribution and has been recorded in more than 85 sites in North America and Asia. Considering the large area of potential habitat for this species, and following the guidelines by Dahlberg and Mueller (2011), population size is projected to be above 400000 mature individuals. There is no evidence of population decline.

Population Trend: Uncertain


Habitat and Ecology

P. dispansus is an annual species. It is usually found in association with conifers, such as Pinus sp. or Abies sp. (Canfield, 1981), but has also been recorded with angiosperms, namely Quercus incana (Ramirez et al., 2022). It has been reported as ectomycorrhizal and as saprotrophic, found growing on wood buried in the soil and causing brown rot decay (Audet, 2010 and Canfield, 1981).

Temperate Forest

Threats

There are no major threats for this species.


Conservation Actions

No specific conservation measures are needed for this species.


Research needed

Further research into the ecology and trophic mode for this species would be useful to improve estimates of population size.
