is the third largest rust genus of the order with more than 200 described species. It is an important rust genus that has undergone tremendous taxonomic changes. This genus produces teliospores united into a head on a compound pedicel composed of two to several hyphae with autoecious, macro-, demi- to hemi-, and, more rarely, microcyclic modes of their life cycle which provide it a unique identity and have proved helpful in the identification of the genus. The current understanding of the taxonomy, history, diversity and distribution of this genus is discussed in this paper. Both online and offline resources were searched to gather data of the published literature. The data thus obtained were analyzed for numerical and graphical summaries to provide the diversity and distribution of the genus. In addition, a phylogenetic analysis based on the ITS and nLSU DNA sequence data available in GenBank and the published literature was performed to examine the taxonomic placement of different species within the genus. The genus was reported to be distributed over 53 countries of the world. Around 51 plant genera belonging to four plant families, viz., , , and were found to be infected with these rust fungi. The phylogenetic analysis based on LSU and ITS sequence data revealed the polyphyletic nature of the genus. A table of 248 species of this genus is also provided with all information of host, distribution and cited reference that can be helpful for mycologists to find all information at one place. Future perspectives for the advancement of this genus are also discussed.
是该目第三大锈菌属，已描述的物种超过200种。它是一个重要的锈菌属，经历了巨大的分类学变化。该属产生冬孢子，冬孢子在由两到几根菌丝组成的复合梗上联合成头状，其生活史有自交、全型、半型到全型，以及更罕见的微型循环模式，这赋予了它独特的特征，并已证明有助于该属的鉴定。本文讨论了对该属分类学、历史、多样性和分布的当前认识。通过搜索在线和离线资源来收集已发表文献的数据。对如此获得的数据进行数值和图形汇总分析，以提供该属的多样性和分布情况。此外，基于GenBank中可用的ITS和nLSU DNA序列数据以及已发表文献进行了系统发育分析，以研究该属内不同物种的分类地位。据报道，该属分布于世界53个国家。发现约51个属于四个植物科的植物属，即 、 、 和 ，受到这些锈菌的感染。基于LSU和ITS序列数据的系统发育分析揭示了该属的多系性质。还提供了该属248个物种的表格，其中包含寄主、分布和引用参考文献的所有信息，这有助于真菌学家在一个地方找到所有信息。本文还讨论了该属未来的发展前景。
