单型属Leifia以前被认为是Odonticium的后来的同义词。根据另外四个东亚标本提供的形态学和系统发育学证据，我们建议将Leifia恢复为膜壳目中的一个独立属。Leifia与Odonticium在形态上的区别在于其具有菌丝链的大形膜囊，许多厚壁囊，顶端内陷，以及狭窄而厚壁的担子。根据ITS和28S区的数据分析，Leifia与Odonticium形成了姐妹进化枝。在Leifia分支的属型Leifia flabelliradiata之外，还新引进了2个采自湖北的标本，命名为Leifia brevispora。该新种为Leifia属的第二种，与属型的区别在于担孢子较短，分布于东亚暖温带至亚热带地区。从越南达拉特采集的另外两个标本在形态上彼此不同，也不同于Leifia的已知物种，但在进一步的分类决定之前需要检查更多的样本。
The monotypic genus Leifia was previously considered to be a later synonym of Odonticium. With the morphological and phylogenetic evidence provided by an additional four East Asian specimens, we propose to reinstate Leifia as an independent genus in Hymenochaetales. Leifia morphologically differs from Odonticium by its grandinioid hymenophore with hyphal strands, numerous thick-walled cystidia with an invaginated apical end and narrowly and thick-walled basidia. The phylogeny generated from the current data set of ITS and 28S regions indicates that Leifia forms a sister clade to Odonticium. Besides the generic type Leifia flabelliradiata in the Leifia clade, two specimens, collected from Hubei, Central China, are newly introduced as Leifia brevispora. This new species is the second species of Leifia and differs from the generic type by its shorter basidiospores and distribution in warm-temperate to subtropical areas in East Asia. The additional two specimens, collected from Da Lat, Viet Nam, differ morphologically, both from each other and from known species of Leifia, but more samples need to be examined before further taxonomic decisions can be made.
