High‐performance liquid chromatography (HPLC), alone or in combination with mass spectrometry (MS), was used to screen the basidiomycetous yeasts Rhodotorula minuta and R . slooffiae isolated from lakes for the presence of UV‐absorbing compounds. Mycosporine‐glutaminol‐glucoside (maximum absorption, 310 nm), a UV‐photoprotective mycosporine known in terrestrial fungi, was the major UV‐absorbing compound found in these species. This is the first identification of a mycosporine in yeasts. The presence of this compound seems to be a promising chemotaxonomical marker for yeast systematics.
