Dimerella pineti (Ach.) Vězda

Thallus very thin, effuse, scurfy, green-grey to geenish black but may ± disappear apparently to leave only the apothecia; apothecia fleshy, short-lived (winter-spring), to 0.5mm in diameter, translucent-pallid to pinkish or sometimes pale orange, sometimes accompanied by white pycnidia. Widespread but minute and easily overlooked, on shaded bark, sometimes on other substrates, including soil.
