Cladia inflata

Cladia inflata is a species of fruticose lichen in the family Cladoniaceae. This lichen forms densely interwoven, spreading mats up to 5 centimetres high, with swollen, glossy branches that vary from pale yellow-brown to olive-brown in colour. It grows on peaty or sandy soil in high-rainfall areas, typically in areas exceeding 3000 millimetres of annual precipitation, and is found across Tasmania, south-eastern mainland Australia, and New Zealand. The species is characterized by its inflated branches that are broader at the forks, a feature that distinguishes it from closely related species in the Cladia aggregata complex....read more on Wikipedia.
