| 英文摘要 |
Lepra picrolichenica sp. nov., collected from Guangxi and Guangdong Provinces in China, is described and illustrated. The new species is distinguished by the cylindrical fragile isidia with pink or orange-red rounded apices and presence of picrolichenic acid. Four species of the lichen genus Pertusaria s.lat. are transferred to the genus Lepra Scop., and diagnostic characteristics of each species are briefly described. A key to all 14 isidiate species of Lepra lacking xanthones and occurring on bark is also provided. |
