A trio of endemic New Zealand lichens: Pannaria aotearoana and P. gallowayi, new species with a new chemosyndrome, and their relationship with P. xanthomelana
The endemic New Zealand lichen Pannaria xanthomelana has been restudied and found to be characterized by a secondary chemistry of pannarin and porphyrilic acid in addition to terpenoids, and by always having abundant, conspicuously large, and mostly foliose cephalodia. Its verruciform pycnidia and b...
