Here are a couple that caught my eye. The yellow one I found today in the prime of life, after 9.5mm of rain overnight. It was on a dead branch, Casuarina, I think. It's possibly Teloschistes species.

This next one is sometimes called "coral lichen" for obvious reasons! It's a ground-dweller and Cladia species. There is a Cladia known as East Coast Snow and that's exactly what this one looks like when you stumble into a large colony of the stuff!
