The species is known from only two records, one in the Philippines and the other in central China.  In both cases it was found in subtropical or tropical moist forest. It is likely that the species occurs in other countries. Because the known habitat is not distinctive or thought to be rare, it is possible that the species is much more widely distributed but with only two records the distribution and population size is impossible to estimate.  Thus, the species is assessed as DD.

Polyporus mangshanensis has a solitary, corky when dry basidiocarps with dark brown stipe and beige to yellowish-orange pileal surface and slightly radial stripes, and brown beige to olive brown pore surface.

The fungus has no recorded occurrence in GBIF.

First reported in Mangshan Nature Reserve, Hunan Province, Yizhang County, China. Also, collected at the foot of Mt. Pulag, Kabayan, Benguet Province, Philippines.

Species reported only twice, once in 2014 where the species was first described in Hunnan Province, China and in 2019 from Mt. Pulag, Benguet, Philippines. The number of individuals is not indicated in these studies and there are no reported occurrence in GBIF or iNaturalist.

Species is found on living wood at the foot of Mt. Pulag, Benguet, Northern Philippines. Mt. Pulag has a pine forest at the base, growing on barren, rocky slopes. At lower elevation, the mountainside has a mossy forest while the summit is covered by grassland and dwarf bamboos. Species was first reported from a fallen angiosperm branch in Mangshan Nature Reserve, Hunan Province in China. The nature reserve belongs to the Castanopsis–Altingia Forest Domaine of the Nanling Hilly Area, southern sub-zone of subtropical evergreen broadleaf forest zone. Based on these two records, the species does not appear to be restricted to a rare or restricted habitat and it is assumed that the species likely has a much broader distribution.

Species occurred in a nature reserve and national park.  In the Philippines the site has some tourist activities that may disturb the habitat.  There are also indigenous communities living in the area that are clearing land for farming and using the forest for hunting and collecting plant material. There are occasional large forest fires in the area.  Threats for the site in China are not documented.

The two documented records of this species occur in protected areas. The species likely occurs in additional sites outside of protected areas so habitat protection is needed.

There is a for surveys to documented the distribution and population size of the species. There are no records in GBIF or iNaturalist. Information on its ecology, distribution, and potential uses is lacking.

No recorded uses.
