The holotype of Thyronectria hyperantarctica was re-examined, redescribed, and compared with new collections of an Antarctic bryophilous ascomycete from a similar area. Because the condition of type material was insufficient for molecular studies, the authors designated an epitype from newly collected material with a high degree of morphological similarity to the holotype and paratype material. Phylogenetic analysis of the epitype revealed that its closest phylogenetic affinity was with the family Tilachlidiaceae and it formed a monophyletic group in this lineage within other collections of the species. Therefore, the new monotypic genus Psychronectria is described to accommodate Thyronectria hyperantarctica. The fungus is superficially similar to Thyronectria species in Nectriaceae, but the ascospores differ in color, size, and type of septation.
对南极甲状腺菌（Thyronectria hyperantarctica）的正模标本进行了重新检查、重新描述，并与来自类似区域的一种南极嗜苔藓子囊菌的新采集样本进行了比较。由于模式标本的状况不足以用于分子研究，作者从新采集的与正模标本和副模标本具有高度形态相似性的材料中指定了一个新模式标本。对新模式标本的系统发育分析表明，它与蒂拉克利德科（Tilachlidiaceae）的亲缘关系最为密切，并且在该物种的其他采集样本中，它在这个谱系中形成了一个单系类群。因此，描述了新的单型属Psychronectria来容纳南极甲状腺菌。该真菌在外观上与肉座菌科（Nectriaceae）中的甲状腺菌属物种相似，但子囊孢子在颜色、大小和隔膜类型上有所不同。
