This crustose lichen was observed growing on the trunk of a Quercus agrifolia. The host wild tree is estimated at about twenty years old and is around 22 cm DBH. The size of this patch of lichen is about three cm across, although there are numerous similar looking patches on the tree trunk. This specimen is without noticeable taste, in particular no bitter taste.
This lichen specimen was seen cohabiting the Quercus douglasii twig with several other (mostly foliose) lichen species.
