    Polysporina gyrocarpa, a crustose lichen Found this at White Pocket, Arizona on the Navajo sandstone. I've seen a suggestion that it is a tile lichen which I can see but it's suggested that it is Lecidea tessellata which eventually dissolves the rock using acids and leaves an etching in the rock. Other photo below shows that effect, at bottom left. However to me this does not look like Lecidea tessellata as the apothecia seems far too regular compared to what appears visible here??? Any experts to help, never seen anything like this anywhere else and this was only in one small area here.<br /> <br /> https://www.jungledragon.com/image/109605 Arizona,Polysporina gyrocarpa,Vermilion Cliffs,White Pocket,crustose lichen
