#631 - Teloschistaceae family - Golden Lichens

A family of usually bright yellow, orange, or red lichenised fungi, often with even brighter apothecia. This one, for example, that was growing profusion on bare branches in a Mandurah golf course, seems similar to Teloschistes chrysophthalmus, the Gold Eye Lichen.

Other lichens in the family include the Orange Wall Lichen, or Sunburst Lichens.
