摘要Hypogymnia属植物的形态特征为叶肿胀，髓质中空，下表面有穿孔，无根。在对Hypogymnia spp.在35种植物的下表面偶见有根茎和菌丝。附属器官的形态和解剖学进行了研究，使用解剖，复合和扫描电子显微镜，并与根茎中发现的相关属Arctoparmelia。在Hypogymnia中发现了两种类型的根茎状结构：细长的根茎和粗短的触片，两者数量都很少，并且稀疏地分布在下表面。两种植物的根茎形态无明显差异，但熊梅属植物根茎丰富。在Parmeliaceae中，Hypogymnia与Arctoparmelia，Brodoa和Pseudevernia一起属于hypogymnioid分支，其中大多数被认为缺乏根茎。在Hypogymnia的根茎的发生是一致的放置Arctoparmelia hypogymnioid分支的基础上的分子数据。
Abstract The genus Hypogymnia is morphologically characterized by swollen lobes, a hollow medulla, perforations in the lower surface, and the absence of rhizines. In our studies on Hypogymnia spp. we found rhizines and hapters were occasionally present on the lower surface of 35 species. Morphology and anatomy of the appendage-organs were studied using dissecting, compound, and scanning electron microscopy and compared with rhizines found in the related genus Arctoparmelia. Two types of rhizine-like structures were found in Hypogymnia: slender and elongated rhizines, and thick and short hapters, both of which were few in number and sparsely distributed on the lower surface. There are no obvious differences in the morphology of rhizines between Arctoparmelia and Hypogymnia, except that rhizines are abundant in Arctoparmelia. Within Parmeliaceae, Hypogymnia belongs to the hypogymnioid clade together with the genera Arctoparmelia, Brodoa, and Pseudevernia, most of which are considered to lack rhizines. The occurrence of rhizines in Hypogymnia is consistent with the placement of Arctoparmelia in the hypogymnioid clade based on molecular data.
