Myriotrema rugiferum thallus and apothecia.

Members of the genus Myriotrema are often called volcano lichens due to their miniature likeness to the real thing. Apothecia are set at the bottom of deep craters and function as normal apothecia although they certainly resemble  perethecia with ostioles.
