摘　　要：本研究报道一个中国红菇属新记录种——印度碗状红菇(Russula indocatillus)。文中提供了该物种详细的形态学描述、线条图以及系统发育分析,并且与近缘种进行了比较。印度碗状红菇的主要形态学特征为:棕黄色到赭黄色的菌盖中央,奶油黄色到淡黄色的菌盖边缘,孢子印白色到奶油色,担孢子近球形到宽椭圆形到椭圆形,表面具圆锥状或近圆柱状孤立的疣,单细胞的盖表囊状体,短而纤细,有分叉和分隔的菌盖表皮末端细胞。综合形态学特征和系统发育分析,表明印度碗状红菇属于红菇属异褶亚属劣味组(Russula subg.Heterphyllidia sect.Ingratae)。Russula indocatillus was reported as new species to China.A detailed morphological description,illustrations and phylogeny are provided,and comparisons with related species are made.It is morphologically characterized by a brownish orange to yellow ochre pileus center with butter yellow to pale yellow margin,white to cream spore print,subglobose to broadly ellipsoid to ellipsoid basidiospores with bluntly conical to subcylindrical isolated warts,always one-celled pileocystidia,and short,slender,furcated and septated terminal elements of pileipellis.The combination of detailed morphological features and phylogenetic analysis based on ITS-nrLSU-RPB2 sequences dataset indicated that the species belonged to Russula subg.Heterphyllidia sect.Ingratae.
