Cladia retipora (Coral lichen)

Common name: Coral lichen, Snow Lichen
Cladia retipora is a clathrate (latticed) fruticose lichen that grows on the ground and is native to Australia and New Zealand. It sometimes grows in pulvinate clumps to 0.5 m wide or usually as scattered clusters 3–4 cm wide, to 5 cm high. It often grows with moss and large mats can look like snow. Hence another common name “Snow lichen”.
The branches have delicate open-work structure. The network of holes are called fenestrations. This lichen is usually white to pale grey and sometimes there is a yellowing at tips.
The tiny brownish-red tips on the branches are the fungal component's fruiting bodies called apothecia. These produce the spores.
