Lichen Flora on the Genera Alectoria, Pseudephebe, and Sulcaria (Lichenized Ascomycota, Parmeliaceae) from the Hengduan Mountains in China (4)

摘要

Alectorioid lichen specimens used in this study were collected since 1981, mainly from the Hengduan mountain region, all the specimens were examined using standard microscopic techniques and hand-sectioned under dissecting microscope, secondary metabolites were identified by TLC. After detailed taxonomical and chemical study of our specimens and the type specimens, Sulcaria virens var. forrestii is found to have same diagnostic characters with 5. virens except for the diameter of the main branch, thus, it is treated as the synonym of S. virens. Alectoria ochroleuca, Pseudephebe pubescens, and S. virens have rather restricted distribution in Hengduan Mountains, they are considered as rare lichens. Taxonomic characters together with distribution map and key to Alectorioid lichens are provided in this paper. All the specimens involved in this study are deposited in Herbarium of Kunming Institute of Botany (KUN).
