Abstract

In this report, we describe three novel asexual basidiomycetous yeast species, sp. nov. (type strain CBS 10872 =SDY 081), sp. nov. (type strain CBS 10871=SDY 022) and sp. nov. (type strain CBS 10873 =SDY 190), which were isolated from acid rock drainage collected at the São Domingos mine in southern Portugal. Phylogenetic analysis of molecular sequence data indicated that the novel species belong to the order Filobasidiales of the class Tremellomycetes and form a well-separated clade, next to and . Since the novel species also share a peculiar ecology, being able to thrive under extreme environmental conditions characterized by very low pH and high concentrations of heavy metals, we designate this combination of phylogenetic and ecological characteristics as an ecoclade.
