This study aimed to investigate the morphological characteristics and phylogenetic relationships of three new species of from the southern parts of India. The analyses of the ITS and nLSU regions revealed the novelty of these species, which have been named , , and . All three species possess pileate basidiomes, a monomitic hyphal system in the context, and the presence of cystidioles and setae. However, they differ significantly in their phylogenetic placements and other morpho-taxonomic features. is characterized by a meagrely ungulate basidiome, indistinct zones, and an obtuse margin. has a triquetrous basidiome and a radially cracked, crusted pileal surface with an acute margin, while is distinguished by an imbricate, perennial basidiome with an abundantly warted pileal surface. A phylogenetic tree is provided to show the placement of the three new species, along with detailed descriptions and illustrations. Additionally, a key for the identification of the Asian species of is presented.
本研究旨在调查来自印度南部的三个新物种的形态特征和系统发育关系。对ITS和nLSU区域的分析揭示了这些物种的新颖性，它们已被命名为 、 和 。所有这三个物种都具有菌盖状担子果，菌肉中有单系菌丝系统，以及囊状体和刚毛。然而，它们在系统发育位置和其他形态分类特征上有显著差异。 的特征是担子果呈微薄的蹄状，区域不明显，边缘钝圆。 有三棱形担子果，菌盖表面有放射状裂纹和硬皮，边缘尖锐，而 的特征是覆瓦状、多年生担子果，菌盖表面有大量疣状突起。提供了一棵系统发育树以显示这三个新物种的位置，以及详细的描述和插图。此外，还给出了亚洲 物种的鉴定检索表。
