Abstract
The genus Meira currently contains three recently described species of mite-associated basidiomycete yeasts from Israel and Japan and is placed in the Exobasidiomycetes (Ustilaginomycotina) Incertae sedis. A previously undescribed species of Meira was isolated from the phylloplane of a magnolia leaf in Louisiana, USA. Herein, we describe Meira miltonrushii sp. nov. and include phylogenetic analyses from three rDNA loci to resolve the placement of Meira. This study provides evidence that Meira belongs to the family Brachybasidiaceae in the Exobasidiales and supports the placement of another mite-associated yeast genus, Acaromyces, within Cryptobasidiaceae (Exobasidiales). We also examine sequences produced by numerous environmental studies that suggest Meira species can be found as endophytes of many plant species. To our knowledge, this is the first record of a member of the genus Meira in North America.
