This name is not published and the species is Phellinus sarcites. Actually, it is a Fuscoporia species (data not yet published).

Fuscoporia inonotoides is a polyporoid fungus that frequently grows in clusters. It has bright yellowish colors in basidiomata, making the species rather conspicuous in the field. It was discovered very recently during surveys in the Cloud Forests and associated vegetations of Southern Brazil, and there are only 10 collections. The Cloud Forests are under an array of various threats for being a naturally small and fragmented vegetation, very susceptible to threats. In Southern Brazil the Cloud Forests are part of the Atlantic Forest domain, one of the Hotspots for conservation. Although it is possible that this species occurs in other fragments of Cloud Forests in Brazil, we expect that the population of this species is very small and restricted.

Fuscoporia inonotoides is assessed as Vulnerable (VU) C2a(ii), having an inferred population of 10.000 mature individuals.

Fuscoporia inonotoides is currently known only from Cloud Forests of the Atlantic Forest vegetational domain, Southern Brazil. It is also expected to be found in other Cloud Forests fragments scattered throughout south and southeastern Brazil.

Fuscoporia inonotoides is a conspicuous bracket fungus, but there are only ten collections from a single site in the Cloud Forest of the Atlantic Forest vegetation domain in Southern Brazil. It is possible that this species also occurs in other Cloud Forest patches of southern and southeastern Brazil. Regarded as a biodiversity hotspot, the Atlantic Forest domain is considered a high-priority environment for conservation actions due to its high diversity, endemism rates and habitat loss (Myers et al. 2000). Cloud Forests of this domain are restricted to small sized patches, and are dependent on rare microclimatic conditions (Bruijnzeel et al. 2010, Oliveira et al. 2014), making it one of the most susceptible ecosystems to threats caused by climate change (Salazar et al. 2007, Williams et al. 2007, Goldsmith et al. 2013, Gotsch et al. 2014, Pompeu et al. 2014). Moreover, data from the current status of forest coverage (e.g., in Santa Catarina) shows that the mixed needle-broadleaved Araucaria forest, where most areas of Cloud Forests are found, is highly fragmented, with only 21% of forest coverage remaining. Patches of 50 ha or less represent 82% of these remaining forests (Fundação SOS Mata Atlântica 2009, Vibrans et al. 2013). Fuscoporia inonotoides can potentially be found at an estimated 100 sites within one subpopulation. Each of these site may support up to 50-100 mature individuals resulting in an estimated total population size of no more than 10,000. Due to the threats facing Cloud Forests in Southern Brazil, including grazing, increased fire frequency, and shrinking of habitat due to reduced rainfall as a result of climate change, the population is expected to continue to decline by 10-20%  over the next three generations, driven mainly by loss of required habitat.

Fuscoporia inonotoides grows on dead wood and on trunks of living angiosperms (i.e. Myrceugenia spp.). It is restricted to Cloud Forests of the Brazilian Atlantic Forest, in southern and possibly southeastern Brazil.

Fuscoporia inonotoides occurs in Cloud Forests of the Brazilian Atlantic Forest. These forest patches are threatened by human activities such as cattle grazing, introduction of invasive species, anthropogenic fire and land use changes (Brooks & Balmford 1996, Tabarelli et al. 2006, Pinto et al. 2006) plus changes in temperature and moisture due to climate change (Salazar et al. 2007, Williams et al. 2007, Goldsmith et al. 2013, Gotsch et al. 2014, Pompeu et al. 2014), resulting in a continuous decline of its required habitat, even in Protected Areas.

Even though the only known site where F. inonotoides is found is in a protected area, much of its potential habitat faces anthropogenic-related threats. Enforcement of the conservation and protection of known sites, as well as unprotected Cloud Forests fragments in Brazil are needed.

Additional surveys in other sites of Cloud Forest in southern and southeastern Brazil are needed to understand its distribution and possible host specialization. Revision of herbarium specimens may also reveal additional records of this species.
