The lichen has a thick, yellowish-white to greyish-green thallus with a roughened to uneven surface texture. The medulla is white to yellowish. The apothecia, which are immersed in thalline warts, are up to 2 mm in diameter with an ostiole up to 0.5 mm wide. Ascospores number 2 or 4 per ascus (sometimes 6); they are fusiform (spindle-shaped) and muriform, measuring 55–110 by 15–28 μm.[2]
