A survey was conducted of the rust fungus Gymnosporangium in Korea. We recollected previously known species, namely Gymnosporangium asiaticum, G. clavariiforme, G. globosum, G. japonicum and G. yamadae. Gymnosporangium nidus-avis and G. sabinae are reported for the first time from Korea, and two new species, G. monticola sp. nov. and G. unicorne sp. nov., are recognized. Previous single reports of G. miyabei and G. shiraianum could not be confirmed. The LSU rDNA was sequenced from freshly collected specimens. Phylogenetic analyses show that species of Gymnosporangium form a monophyletic group with strong bootstrap support within the rust fungi. The two new species are unique based on both A and B molecular as well as morphological characteristics. Analyses of phenotypic characters mapped onto the phylogenetic tree show that teliospore length followed by telia shape and telia length are conserved; these are morphological characters useful in differentiating species of Gymnosporangium. Each of the nine species of Gymnosporangium in Korea is described and illustrated, and keys based on aecia and telia stages are provided. Lectotype specimens for several names described in Gymnosporangium are designated.
对韩国的锈菌裸果锈菌属进行了一项调查。我们重新收集了先前已知的物种，即亚洲裸果锈菌、棒形裸果锈菌、球形裸果锈菌、日本裸果锈菌和山田裸果锈菌。鸟巢裸果锈菌和萨宾裸果锈菌首次在韩国被报道，并且确认了两个新物种，即山地裸果锈菌新种和独角裸果锈菌新种。先前关于宫部裸果锈菌和白井裸果锈菌的单一报道无法得到证实。从新采集的标本中对 LSU rDNA 进行了测序。系统发育分析表明，裸果锈菌属的物种在锈菌内形成了一个具有强自展支持的单系类群。这两个新物种在 A 和 B 分子以及形态特征方面都是独特的。映射到系统发育树上的表型特征分析表明，冬孢子长度其次是冬孢子堆形状和冬孢子堆长度是保守的；这些是有助于区分裸果锈菌属物种的形态特征。描述并说明了韩国的九种裸果锈菌中的每一种，并提供了基于性孢子器和冬孢子阶段的检索表。指定了裸果锈菌属中几个名称的模式标本。
