<p>The rosette-forming <strong>thallus</strong> of this lichen is 3-10(-20) cm wide with rounded lobes. The <strong>upper surface</strong> is wrinkled and pitted, with granular soredia and is colored olive- or yellow- brown to grey-black when dry, becoming greenish-, bluish-, or reddish-brown when wet. White maculae can be seen on the upper surface with a 10x lens. The medulla is white, and this lichen contains <em>Nostoc</em> as a photobiont. The <strong>lower surface</strong> is a light creamy tan color at margins that lack tomentum, and brown or black tomentose in other areas. The lower surface also has conspicuous white pseudocyphellae (Galloway, 1992; Galloway & Arvidsson, 1990).</p>

This lichen grows in humid, shaded forests. It grows on small trees and shrubs, frequently on thinner branches where it faces less competition from other epiphytes (Galloway & Arvidsson, 1990). It has also been found on rocks, and in South America, it often occurs with other species of the genus (Galloway, 1992).
