Cutaneotrichosporon cavernicola sister species with same karyotype, ITS sequence similarity above the usual threshold for species boundaries, but scrambling of large-width regions. “If [mating infertility caused by genome rearrangement] is universal, chromosome synteny should be considered the determinant of biological species”
