Two new species (Agaricus tumlingensis, and A. philippei) and one new record (A. kunmingensis) belong to the sect. Rubricosi of the subg. Pseudochitonia, are described from India based on morphological and molecular sequence (nrITS and LSU rDNA) data. Agaricus tumlingensis is distinguished by its medium to large-sized basidiomata, brown to dark brown squamulose pileus, ellipsoid to elongate basidiospores with a range value of 5.5-7.5 × 3.5-4.0 μm, and cheilocystidia measuring 15-34 × 9-17 μm. Agaricus philippei has a dark brown appressed squamulose pileus, ellipsoid basidiospores with a range value of 4.5-5.1 × 2.5-3.0 μm, and cheilocystidia measuring 11-21 × 7-14 μm. Detailed morphological descriptions, illustrations, field photographs of the collected basidiomata, comparisons with morphologically similar species, and phylogenetic analysis results based on the nrITS and nrLSU sequence data are provided.
基于形态学和分子序列（nrITS和LSU rDNA）数据，从印度描述了隶属于假小皮伞亚属红盖组的两个新物种（滕氏蘑菇和菲利普蘑菇）及一个新记录种（昆明蘑菇）。滕氏蘑菇的特征为中型至大型担子果、棕色至深棕色鳞片的菌盖、椭圆形至拉长形的担孢子，大小范围为5.5 - 7.5 × 3.5 - 4.0μm，以及大小为15 - 34 × 9 - 17μm的褶缘囊状体。菲利普蘑菇有深棕色紧贴的鳞片菌盖、椭圆形担孢子，大小范围为4.5 - 5.1 × 2.5 - 3.0μm，以及大小为11 - 21 × 7 - 14μm的褶缘囊状体。文中提供了详细的形态描述、插图、所采集担子果的野外照片、与形态相似物种的比较，以及基于nrITS和nrLSU序列数据的系统发育分析结果。
