A less common species of subalpine rock, G. concinnatum occurs as white wormy shoots to 2 cm long that occasionally branch as they loosely wend along the bases and in the crevices of bedrock. It has leaves that are pale whitish-green, tightly overlapping and made up of two equal lobes that terminate in a point. Under the microscope, oil bodies will be present in fresh leaves.
