Dendrobium officinale (Orchidaceae) is a traditional Chinese medicinal plant. Its growth is slow, however many dark septate endophytic fungi (DSEs) are considered useful to plant growth and as biocontrol agents against plant pathogens. The goals of this study were to identify a new DSE and evaluate its plant-growth promotion characteristics. Based on morphological and molecular phylogenetic evidence, a DSE fungal strain TK815 isolated from Dashiwei Tiankengs in Leye county Guangxi Province, China, was classified as a novel genus in the order Cheatothyriales, namely Tiankengomelania gen. nov. typified with T. guangxiense sp. nov. Tiankengomelania guangxiense TK815 can significantly promote the growth of D. officinale in stem length (11.25%), seedling height (16.97%), root length (10.34%), and dry weight (41.05%). This study discovered, described, and illustrated a new DSE fungus, and evaluated its biological function in contributing to the growth and production of the Chinese medicinal plant D. officinale.
铁皮石斛（兰科）是一种传统的中药植物。然而，许多深色隔孢腔真菌（DSE）被认为对植物生长有益，并可用作植物病原菌的生物防治剂。本研究的目的是鉴定一种新的 DSE 并评估其促进植物生长的特性。基于形态学和分子系统发育证据，从中国广西乐业县大石围天坑中分离出的 DSE 菌株 TK815 被归类为 Cheatothyriales 目中的一个新属，即 Tiankengomelania 属，其模式种为 T. guangxiense sp. nov.。Tiankengomelania guangxiense TK815 可显著促进铁皮石斛茎长（11.25%）、苗高（16.97%）、根长（10.34%）和干重（41.05%）的生长。本研究发现、描述和说明了一种新的 DSE 真菌，并评估了其在促进中国药用植物铁皮石斛生长和生产中的生物学功能。
