Fungus and Lichen

Is it a fungus or a lichen?

A lichen is a symbiotic relationship between a fungus and an alga. A lichen is typically greenish in colour, reflecting the chorophyll of the algal component. However, some are pigmented (particularly orange or brown), but in any case a lichen looks very different from the classic toadstool or mushroom fruiting body of a fungus.

This site does not cover fungi that cannot readily be seen with the naked eye, such as aquatic or parasitic fungi. 

For other specimens, this should be regarded as a photographic field guide rather than as a rigorous biological classification of Tasmanian fungi and lichens. For further information on the formal classification of fungi, including those that form lichens, see this article in Britannica
