Common Name(s)

String-of-sausage lichen

Description & Identification

One of the few readily identifiable green/grey beard lichens when well grown. Its straggly, hair-like, tangled, usually unattached stems that can be up to a metre long, swell at intervals along the main branches to create small green/grey sausage-like strings c 3mm in diam. Young material without pronounced swellings could be confused with other species but in U. articulata the medulla reacts by going red with Pd.
