Armillaria altimontana, previously considered North American biological species (NABS) X, is described as new. To date, it appears that A. altimontana prefers higher-elevation, mesic sites within the dry, conifer forest zone of western interior North America. This species has been found on hardwoods and conifers and is associated most commonly with Abies-dominated forest types in southern British Columbia, Washington, Oregon, Idaho and northern California. Partial elongation factor 1-alpha (tef1) sequences were generated from six isolates of A. altimontana originating from three locations in northern Idaho. Phylogenetic analyses of all 10 North American Armillaria species were carried out with maximum parsimony and maximum likelihood. Results indicate that isolates of A. altimontana formed a monophyletic group and clustered with A. calvescens, A. cepistipes, A. gallica and A. nabsnona, which is in agreement with recent phylogenetic studies of Armillaria.
高山蜜环菌，以前被认为是北美生物种（NABS）X，被描述为新种。迄今为止，高山蜜环菌似乎更喜欢北美西部内陆干旱针叶林带中海拔较高、湿度较大的地点。该物种存在于硬木和针叶树中，最常见于不列颠哥伦比亚省南部、华盛顿州、俄勒冈州、爱达荷州和加利福尼亚州北部以冷杉为主的森林类型中。从爱达荷州北部的三个地点采集的六个高山蜜环菌分离株生成了部分延伸因子 1-α（tef1）序列。对所有 10 种北美蜜环菌进行了最大简约法和最大似然法的系统发育分析。结果表明，高山蜜环菌的分离株形成了一个单系群，并与 A. calvescens、A. cepistipes、A. gallica 和 A. nabsnona 聚类，这与最近的蜜环菌系统发育研究结果一致。
