根据形态特征、ITS1-5.8S-ITS2 rDNA序列分析、5基因（nrSSU、nrLSU、tef-1 α、rpb1和rpb2）序列分析和MAT1-2-1基因序列分析，对采自云南省兰平县的一新种Ophiocordyceps lanpingensis进行了描述。本种间质较薄，被周较小，子囊孢子较薄（多裂短间隔）。基于ITS、5基因和MAT1-2-1基因数据的系统发育分析表明，兰平棘球鼠与罗伯特棘球鼠和中华棘球鼠的进化关系最密切，但仍有明显的距离。形态学特征和系统分析均表明，该种为蛇虫草属新种。(C) 2013爱思唯尔有限公司版权所有。
A new species of Ophiocordyceps, Ophiocordyceps lanpingensis collected from Lanping County, Yunnan Province, southwestern China, was described based on morphological characteristic, ITS1-5.8S-ITS2 rDNA sequences analyses, 5-gene (nrSSU, nrLSU, tef-1 alpha, rpb1 and rpb2) sequences analyses and MAT1-2-1 gene sequences analyses. This species was characterized by thinner stroma, smaller perithecium, thinner ascospore (multiseptate with short septation). The phylogenetic analyses based on the ITS, the 5-gene and MAT1-2-1 gene dataset showed O. lanpingensis had the closest evolution relationship with O. robertsii and O. sinensis, but still had obvious distances to them. Both morphological character and systematic analyses supported that O. lanpingensis was a new species of Ophiocordyceps. (C) 2013 Elsevier GmbH. All rights reserved.
