用扫描电镜观察，中国种印度块菌和印度块菌的样品均为假阳性。sinense与T. pseudohimalayense、T. indicum，Duthie于1899年在印度采集，并将样品重新命名为T. 1988年的喜马拉雅山。不同的作者谁命名的四个分类群（T。indicum，T. himalayense，T. sinense，T. pseudohimalyense）描述了包被表面的差异，这些差异可以被认为是单个物种内的常见变异。我们认为T. indicum，T. himalayense，T. sinense和T. pseudohimalayense为一种，T.印度在这个T。根据ITS序列和β-微管蛋白序列分析，将中国分离的两个类群划分为两个地理生态型。这项研究是第一次确定中国块茎物种的遗传和地理结构。(c)2006年英国真菌学会。由爱思唯尔有限公司出版。保留所有权利。
When examined using SEM, Chinese samples of Tuber indicum and T. sinense displayed the same ascospore ornamentation as that of T. pseudohimalayense, T. indicum, collected in India by Duthie in 1899, and samples renamed T. himalayense in 1988. The different authors who named the four taxa (T. indicum, T. himalayense, T. sinense, T. pseudohimalyense) described differences in the surface of the peridium which could be considered as usual variations within a single species. We consider T. indicum, T. himalayense, T. sinense and T. pseudohimalayense as one species, T. indicum. Within this T. indicum complex, according to ITS and beta-tubulin sequences, there are two groups in China, which could be considered as geographical ecotypes. This study is the first to identify a genetic and phylogeographical structure within the Chinese Tuber species. (c) 2006 The British Mycological Society. Published by Elsevier Ltd.
