Assessment Notes

Taxonomic notes

As a result of recent molecular analyses, the species was transferred to Neodyctiopus. Polyporus dictyopus is characterized by having basidioma laterally stipitate, with short, robust, black, and reticulated stipe, margin irregular, wavy and lobed, variable pilear surface color, and subcylindrical to rarely narrowly cylindrical basidiospores. The species may be similar to N. atlanticae, but differs by the short, robust, and lateral stipe, and the smaller basidiospores (Palacio et al. 2017).


Why suggested for a Global Red List Assessment?

Subtropical/Tropical Dry ForestSubtropical/Tropical Moist Lowland Forest

Threats

It presents no evident threat, being very common at least in Brazil. However, it is found in the Atlantic Forest, a hotspot, in the Amazonia (currently being deforested at the highest rates in the last decades) and Cerrado (also a hotspot). Also, Caatinga is threatened with desertification.
