Noteworthy species of Stereocaulon from China
中国珊瑚枝属地衣的特殊种

Stereocaulon incrustatum, a new record in China, and St. massartianum and St. sorediiferum have several special chemical races, and the absence of atranorin in the genus is reported for the first time.Investigation results show that chemistry is not very important in taxonomy of the genus. Evolutionally, the cephalodia of St. incrustatum are possibly a transition characteristic from poorly developed cortex to protosacculate cephalodia.
