A novel species of the oligotrophic genus Ochroconis colonizing indoor wet cells

Ochroconis aquatica, a novel species of the melanized genus Ochroconis (Sympoventuriaceae, Venturiales), is recognized by phylogenetic analyses using nuclear ribosomal DNA genes (nuSSU, ITS, nuLSU). It clustered in a clade containing species with mostly 4-celled as a sister of O. anellii, consistent with its morphology but slightly different in growth rate. This novel species is a further colonizer of wet, poor-nutrient indoor environments.
