Himantormia – an Antarctic genus in the Parmeliaceae (lichenized ascomycetes).
The phylogeny of the Patagonian-Antarctic genus Himantormia is investigated with nuclear ITS rDNA sequences in PAUP. The monotypic genus Nimisia is synonymized with Himantormia, and the new combination H. deusta is proposed. The secondary chemistry was investigated using HPLC; protocetraric, stictic, succinprotocetraric and confumarprotocetraric acids were detected in H. deusta for the first time,
