Lecanora cf. praepostera Nyl. - On volcanic rock. TLC: atranorin, norstictic, tr. connorstictic acids (7 specimens tested). The specimens deviate because the apothecia are mostly immersed and without thalline margin. Perhaps a result of excessive snail grazing?

Lecanora sp. 1. ("YellowImmers") - On volcanic rock. TLC: atranorin, xanthones (incl. thiophanic acid?) (1 specimen tested). Shares a yellowish thallus color with L. marginata, but in that species it is caused by usnic acid, not xanthones.

Lecanora sp. 3 ("Pseudotephromela") - On volcanic rock. Apothecia immersed in thallus warts and somewhat resembling Tephromela spp., but without brown hypothecium and purplish hymenium, and with lecanora-type asci. TLC: atranorin, div. indets. incl. 2 depsides (no fatty acid). Not L. cenisia because the chemistry is different.
