Further investigations on Darblshirella gracillima (Kremp.) Zahlbr. an
d Ingaderia pulcherrima Darb. are reported. A new chemotype of D. grac
illima produces lecanoric acid 1, psoromic acid 3, and 2'-0-demethylps
oromic acid 4. Two chemotypes of I. pulcherrima have been detected, on
e producing lecanoric acid 1, erythrin 2, and psoromic acid 3, and the
other yielding only psoromic acid 3.
