Usnea articulata, commonly known as the string-of-sausage lichen, [1] is a pale greenish-grey, densely branched lichen with a prostrate or pendant growth form. It grows on bark, on branches and twigs, and is often unattached to a branch and merely draped over it. It grows up to 100 cm (40 in) in length. [1] The thallus (vegetative tissue) of.

String of sausages lichen Like all lichens this species is sensitive to air pollution, so the unmistakable pale grey-green sausage-like stems of this lichen are now restricted to places untouched by modern industry and road traffic. Remote sites in the south-west, especially in Devon, are the few places in England it can be found.

String-of-sausages lichen (Usnea articulata). The thallus (vegetative tissue) of this fruticose (bush-like) lichen is densely branched, and forms tangled masses of stems which are prostrate or pendulous. The branches are smooth and somewhat knobbly or spiny, and a greenish-grey colour. The larger stems become articulated, dividing into inflated, sausage-like segments.

Habitat. Forests. Woodland. Grows in short tufts (to 10 cm) of flattened branches with forked tips, often with a net-like pattern of ridges visible on the surface. Pale grey-green to pale yellow-green on the upper side and whitish underneath. This can be harder to see if the lichen has spent some time on the ground or in older specimens.

The branches can be sharply constricted down to the central core to give the appearance of an uneven 'string of sausages'. The cortex is very thin, the medulla wide, lax and cottony. Not fertile in the UK. Identification Chemistry: Medulla K-, KC-, Pd+ red. Similar species: No other Usnea species have the characteristic 'string of sausages'.

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.

String-of-sausages lichen (Usnea articulata) As the name suggests, this lichen resembles a miniature string of sausages, although their glaucous colour is less appetising. Despite its silly name, it tells a tale of a serious problem; like many lichens, the string of sausages is extremely sensitive to air quality and is mainly restricted to.
