Pannaria isidiosa

Pannaria isidiosa is a species of foliose lichen in the family Pannariaceae, described in 2006. Found in montane forests of New South Wales, Australia, it grows on tree bark and occasionally on ferns at elevations between 1200 and 1450 metres. The lichen forms leaf-like rosettes with abundant coral-like reproductive structures known as isidia. It contains a unique combination of secondary metabolites, including pannarin and methylplacodiolic acid, as well as unidentified terpenoids. Closely related to Pannaria xanthomelana, this species is distinguished by its distinctive lemon-shaped spores and complex chemosyndrome....read more on Wikipedia.
