This ‘bark-pimple’ lichen grows exclusively on birch. There is no visible thallus so the tiny, black, spherical discs (0.3-0.5mm diam.) show up as black dots on the bark often with a faint, dark shadow below the disc. From above the discs (perithecia) appear oval. The spores are colourless, curved and one-septate (25-35 x 2-4ųm). Scattered; Northern and western Ireland.
