Taxonomic notes

Rigidoporus vinctus is characterized by pink to black basidiomata, tiny pores (6–12 per mm) and strongly encrusted cystidia. It is related to R. undatus (Pers.) Donk, differing by the colour of the basidiomata (isabelline to beige), larger pores (7–9 per mm) and smooth or only apically encrusted cystidia (Gomes-Silva et al. 2014)
