Graphis scripta (images of British lichens)

A thin, smooth, pale crust with prominent, long, very narrow, curved, often forked apothecia (lirellae), with a grey hymenium and raised, black, unfurrowed margins; spores colourless, with transverse septa only. Widespread and often common on smooth bark. Generally the commonest of a group of very similar species, including species of Graphina and Phaeographis (pages pending), that require microscopic examination for certain identification.
