Abstract english

The lichen genus Allocetraria (Parmeliaceae) includes eight species distinguished by a palisade plectenchymatous cortex, asci with a very broad axial body, globose or subglobose ascospores, and filiform pycnoconidia. Two new species, A. flavonigrescens Thell et Randl. and A. sinensis Gao, are described, and the new combination A. denticulata (Hue) Thell & Randlane, A. globulans (Nyl.) Thell & Randl., and A. oakesiana (Tuck.) Randl. & Thell are proposed. A potaninii (Oxn.) Randl. & Saag is synonymized with A. stracheyi (Bab.) Kurok. & Lai. The anatomy of the genus is carefully described for the first time.
