Tylopilus aquarius, comb. et stat. nov., and its new variety from Brazil

Abstract

We propose the new species and new combination, Tylopilus aquarius var. aquarius, by elevating T. potamogeton v. aquarius to species level. We also describe a new variety, T. aquarius var. megistus, from the Atlantic Forest states Paraiba and Rio Grande do Norte, Brazil, that produces larger, robust basidiomata and smaller basidiospores as compared to T. aquarius var. aquarius.
