摘　　要：本研究以我国西南、华中和华东部分地区变绿红菇近似种类"青头菌"为研究对象,使用形态学和rDNAITS区段核苷酸序列分析相结合的方法进行鉴定。结果表明,"青头菌"多数子实体属于变绿红菇Russula virescens复合群,其余子实体为绿桂红菇R.viridicinnamomea、红边绿菇R.viridirubrolimbata和本文描述的新种拟壳状红菇R.pseudocrustosa。在形态特征和ITS核苷酸序列方面,我国变绿红菇近似种R.aff.virescens与欧洲的变绿红菇R.virescens和北美的小变绿红菇R.parvovirescens均存在一定差异。变绿红菇近似种类在亚洲的分布范围较广,物种准确划分尚需进一步深入研究。Closely related species of Russula virescens complex"qingtoujun"from markets of southwestern,central and eastern China were surveyed.Morphological features and ITS rDNA phylogenetic evidence indicate that"qingtoujun"are complex species having close affinity to R.virescens,intermix with R.viridicinnamomea,R.viridirubrolimbata and R.pseudocrustosa sp.nov.There are discrepancies in morphology and ITS phylogeny between the Chinese R.aff.virescens and European R.virescens and North American R.parvovirescens.The R.virescens species complex has a vast distribution in Asia and delimitation of species needs further studies.
