The 17 described species have been documented primarily on humans and domestic animals, but few studies have examined <i>Malassezia</i> species associated with more diverse host groups such as wildlife. While investigating the skin mycobiota of healthy bats, we isolated a <i>Malassezia</i> sp. that exhibited only up to 92% identity with other known species in the genus for the portion of the DNA sequence of the internal transcribed spacer region that could be confidently aligned. The <i>Malassezia</i> sp. was cultured from the skin of nine species of bats in the subfamily <i>Myotinae</i>; isolates originated from bats sampled in both the eastern and western United States. Physiological features and molecular characterisation at seven additional loci (D1/D2 region of 26S rDNA, 18S rDNA, chitin synthase, second largest subunit of RNA polymerase II, β-tubulin, translation elongation factor EF-1α, and minichromosome maintenance complex component 7) indicated that all of the bat <i>Malassezia</i> isolates likely represented a single species distinct from other named taxa. Of particular note was the ability of the <i>Malassezia</i> sp. to grow over a broad range of temperatures (7-40 °C), with optimal growth occurring at 24 °C. These thermal growth ranges, unique among the described <i>Malassezia</i>, may be an adaptation by the fungus to survive on bats during both the host's hibernation and active seasons. The combination of genetic and physiological differences provided compelling evidence that this lipid-dependent yeast represents a novel species described herein as <i>Malassezia vespertilionis</i> sp. nov.
