(Received on February 12，1 999)
Pustulate or sorediate species of Cetrariastrum are revised. An ew species，C.
chilense，is described from Chile. It is related to C. sorocheilum，a w idely distrib-
uted species，f rom which it is readily distinguished by the presence of rhizines on
the lower surface. The differences between C. columbiense and C. subplanum are
discussed and C. subplanum is reported from eastern Asia. A key to the pustulate
and/or sorediate species of the genus is given.

The present species is quite similar to C.
sorocheilum in having terminal or subtermi-
nal soralia，wh ich sometimes spread over the
upper surface of lobes. However，it is
clearly distinguished from the latter by the
production of gyrophoric acid rather than
salazinic acid in the medulla，as pointed out
by Hale and Wirth (1971).
