A laminated root rot on Qilian juniper (Sabina przewalskii) caused by a species of Phellinidium (Basidiomycota) was observed in northwest China. Seventeen fungal samples collected from Qinghai Province during 2012 and 2013 were used for taxonomic and pathogenicity tests. The fungal pathogen was identified by morphological characters and phylogenetic analyses based on nLSU sequences. A new fungus is described herein as Phellinidium qilianense sp. nov. One-year-old Qilian juniper seedlings were wound-inoculated under controlled conditions to test pathogenicity of the fungal species. The fungus was successfully reisolated from decayed tissue of tested seedlings. P. qilianense is a new forest pathogen on coniferous trees in China.
在中国西北部观察到一种由拟层孔菌属(担子菌门)的一个物种引起的祁连圆柏(Sabina przewalskii)层状根腐病。2012年至2013年期间从青海省采集的17份真菌样本用于分类学和致病性测试。基于nLSU序列,通过形态特征和系统发育分析对真菌病原体进行了鉴定。本文描述了一种新真菌,即祁连拟层孔菌(Phellinidium qilianense sp. nov.)。在可控条件下对一年生祁连圆柏幼苗进行创伤接种,以测试该真菌物种的致病性。该真菌已成功从受试幼苗的腐烂组织中重新分离出来。祁连拟层孔菌是中国针叶树上一种新的森林病原体。
