BACKGROUND
, a genus established in 1818, has been the subject of various taxonomic studies, with revisions leading to the recognition of several genera within the Metzgeriaceae family. Recent research indicates that constitutes over 98% of the family's species, with broad global distribution.
NEW INFORMATION
During a bryophyte survey in Shennongjia National Park, A. Evans was newly recorded in China, expanding the known distribution of this species beyond its previously reported locations in the South Atlantic and South Pacific regions. This represents the first report of in East Asia, specifically in evergreen broadleaf forest habitats. The discovery contributes new insights into the species' morphology, including variability in thallus shape and reproductive structures, distinguishing it from closely-related taxa. A key to species of from Asia is also given.
背景
[属名]于1818年建立，一直是各种分类学研究的对象，修订后导致在美苔科内识别出几个属。最近的研究表明，[属名]构成了该科98%以上的物种，分布广泛。
新信息
在神农架国家公园的苔藓植物调查中，[物种名]A. 埃文斯在中国首次被记录，扩大了该物种已知的分布范围，超出了此前报道的南大西洋和南太平洋地区的分布地点。这是该物种在东亚的首次报道，特别是在常绿阔叶林生境中。该发现为该物种的形态学提供了新的见解，包括叶状体形状和生殖结构的变异性，使其与近缘类群区分开来。还给出了亚洲[属名]物种的检索表。
