Lost Lichens

Lost Lichens

While Lichens are mostly made up of fungal tissue, they are a symbiosis that also includes algae and/or cyanobacteria that do the photosynthesis. Together these live in some of the toughest places on earth. Read more here.

Below are three lichens listed for protection under the Victoria Flora and Fauna Guarantee Act (FFG Act 1988). Despite this there are no new records nor collections in the last two decades for Victoria.

Look-alikes:

Lichens often need to be collected to be properly identified, as chemical tests and microscopic characters may need to be considered. There are many other Shield and Beard lichen species.
