Assessment Notes

Taxonomic notes

Rigidoporus biokoensis resembles R. mariae and R. amazonicus due to the laterally stipitate basidiomata, but the absence of cystidia in R. mariae and the robust basidiomata with larger pores in R. amazonicus distinguish these species from R. biokoensis (Gomes-Silva et al. 2014).


Why suggested for a Global Red List Assessment?
