Megjegyzések:Four strains alternating between yeast and filamentous growth morphologies were isolated from flowers in two regions of Laos. In liquid environment the isolates propagated by budding and developed irregularly shaped pseudohyphae. On solid media their yeast cells switched to hyphal growth which could return to the yeast phase by developing lateral blastoconidia. The sequences of the D1/D2 domains of the large subunit (LSU) 26S rRNA genes, the internal transcribed spacer (ITS) regions and the small subunit (SSU) 18S rRNA genes were identical in the four strains and differed from the corresponding sequences of other yeast species available in databases by at least 11% (D1/D2), 13% (ITS) and 7% (SSU). In an independent project, two strains with D1/D2 and ITS sequences very similar to those of the Laotian strains were found in bark samples collected in Brazil. The six strains also differed from the closest yeast species in physiological properties, indicating that they represented a hitherto undescribed species. The phylogenetic analysis of the D1/D2 sequences, and the concatenated sequences of the SSU rRNA genes, D1/D2 domains of LSU rRNA genes as well as the protein-encoding genes ACT1 and TEF1 placed them close to Hyphopichia. To reflect this position, the novel genus name Metahyphopichia and the novel species name Metahyphopichia laotica are proposed for them. The type strain is 11-1006T (=CBS 13022T = CCY 092-001-001T = NCAIM Y.02126T) isolated in Luang Prabang (Laos). Mycobank registration numbers are MB 808253 (Metahyphopichia) and MB 808254 (M. laotica).
