西藏“亚东黑木耳”的分类地位研究

Taxonomic Status of Yadong-Hei-Mu-Er, a Wild Edible Mushroom from Tibet

"亚东黑木耳"是西藏亚东县的一种野生食用菌,营养丰富,生长于峨眉蔷薇(Rosa omeiensis)的枯枝上,当地群众通过采集和销售这种野生食用菌来提高经济收入。长期以来,"亚东黑木耳"一直被误认为是黑木耳(Auricularia auricula-judae)。通过形态学和分子系统学研究证实,"亚东黑木耳"并非是真正的黑木耳,而是一种黑耳(Exidia sp.)。

Yadong-Hei-Mu-Er is a nutritious edible mushroom that grows in the wild on dead branches of Rosa omeiensis, in Yadong County, Tibet, where its collection and sale provides the local people with additional income. Although Yadong-Hei-Mu-Er has long been considered as Auricularia auricula-judae, we now report a combined morphological and molecular phylogenetic study showing it to be a species of Exidia.
