Description: This ragged, wrinkled, flattened, variably bloated, fruticose, grey to green lichen epiphyte is common on basic-barked trees in well-lit, often isolated situations; parklands, estates, waysides. The lobe ends swell then split open to reveal a floury coating of soredia within. It is common in suitable sites throughout Ireland.

Key Identification Features:

• The ragged, flattened thallus with soralia bursting from splits in the lobe ends serves to distinguish it
• The thallus of Ramalina canariensis is usually hollow, at least in part, whereas that of a lookalike Ramalina lacera is not.
