Assessment Notes

Taxonomic notes

Fomitiporia baccharidis was some times previously reported as F. apiahyna. Fomitiporia baccharidis and F. apiahyna have basidiospores of the same size range [(5.0–) 5.0–6.5 (−7.0)×(4.5–) 5.0–6.0 (−6.0), ave=5.9×5.1 um. However, F. apiahyna forms much harder (woody) basidiomata, with a darker, almost black, pilear surface, flat to convex, narrowly concentrically sulcate with numerous thin and shallow furrows. In section, the pileus has a black crust of variable thickness depending on the age of the basidiomata, covering a homogeneously dense context (Amalfi et al. 2014).

Why suggested for a Global Red List Assessment?

Geographic range

This seems to be a Neotropical species, known in 7 countries. Most reports are from Brazil.

Population and Trends

There are 94 records in 7 countries, most of them in Brazil.

Population Trend: Uncertain

Habitat and Ecology

In Brazil the species is found mainly in Amazonia and Atlantic Forest.
