Coenogonium pineti is a species of crustose lichen in the family Coenogoniaceae. It was first formally described by Erik Acharius in 1810, as Lecidea pineti.[2] Robert Lücking and H. Thorsten Lumbsch transferred it to Coenogonium in 2004 after molecular phylogenetic analysis suggested its placement in that genus. The lichen has a widespread distribution in cooler, temperate regions of the Northern Hemisphere, but has also been recorded from southeastern mainland Australia and Tasmania.[3]
Although usually found growing on bark, Coenogonium pineti has also been found growing on mosses. Its thallus is smooth, greyish-green to greenish-black in colour, and lacks a prothallus; it measures 5–20 mm (0.2–0.8 in) in diameter. The apothecia are small (0.2–0.5 mm in diameter) and pale with a wide margin. Ascospores are ellipsoid with a single septum, measuring 9–14 by 2.3–4.5 μm.[4]
Some preliminary molecular analysis indicates that there are distinct genetic lineages within the traditional circumscription of Coenogonium pineti, suggesting the presence of cryptic species.[5]
