Auriporia aurulenta is a rare lignicolous saprotroph which primarily occurs in mountain old-growth or mature coniferous and mixed coniferous-broadleaved forests. Basidiocarps occur on the wood of large-size coniferous fallen trunks (Pinus, Picea, Abies).
Global red-list assessment: The total number of known localities is around 100-200. As the potential habitat covers a wide area, the number of total sites is estimated at 2000-4000, and the number of mature individuals is estimated to be in between 4,000-8,000 (as usually only one log of the required size and age is found in each locality). The species is restricted to large, mature trees, primarily in montane habitats, and these habitats are in decline. Based on this, the species is assessed as VU according to the C-criterion.

Auriporia aurulenta A. David, Tortič & Jelić is one of the three species considered currently in the genus Auriporia Ryvarden (Polyporales, Agaricomycetes, Basidiomycota). Two other species are A. aurea (Peck) Ryvarden, the type of the genus Auriporia, and A. brasilica G. Coelho.  Based on ITS data, the one record of this species from the US is conspecific, but the habitat is so different that further study with additional genetic markers is warranted.

Increasing anthropogenic impacts on mountain forest ecosystems, including recreational pressure, logging, and the removal of dead wood, are leading to the destruction of habitats for Auriporia aurulenta, a species with strict requirements for large coniferous dead wood in mountain habitats.

The species is known from several countries in Europe (Austria, Croatia, Czech Republic, France, Germany, Poland, Russia (European part), Serbia, Slovakia, Slovenia, Spain, Switzerland, Ukraine), and Asia (China, India, Russia (Asian part). Usually it is restricted to mountain habitats, everywhere it has been recorded as single specimens.  There is one report from the United States, which is not included in this assessment as the described habitat for that specimen indicates that it may represent a distinct species.

Based on available literature and herbarium data, the species has been recorded from single finds within the surveyed localities. The total number of known localities is around 100-200. As the potential habitat covers a wide area, the number of total sites is estimated at 2000-4000. Typically, it is recorded from one log per site. The number of mature individuals (two mature individuals per functional individual, i.e. per trunk or log, c.f. Dahlberg and Mueller 2011) is estimated to be in between 4,000-8,000 mature individual (as usually only one log of the required size and age is found in each locality).  The species is restricted to large, mature trees, primarily in montane habitats, and these habitats are in decline.

Auriporia aurulenta is a lignicolous saprotroph. The species primarily occurs in mountain old-growth or mature coniferous and mixed coniferous-broadleaved forests. Basidiocarps occur on the wood of large-size coniferous fallen trunks (Pinus, Picea, Abies).

As the species needs large dead conifer trunks, logging, removal of dead wood, etc. reduces its required substrata and habitat. Logging of these forests and conversion for recreational development of mountain areas are key drivers of habitat loss.

Site and habitat protection with appropriate management is needed.

Research into the distribution and habitat requirement of the species throughout its range is needed. Based on ITS data, the one record of this species from the US is conspecific, but the habitat is so different that further study with additional genetic markers is warranted.
