General Description

A very common lichen with a pendent, tufted thallus having numerous flattened branches up to 3mm wide and 7cm long. The branches, arising from a single point of attachment, are pale grey-green on both upper and lower surfaces. Fine soredia are found along the margins of the branches in oval soralia. Apothecia are rare.
