Description: The uniform gray material is vitrinite showing remnant plant cell structure that has survived the coalification process. In the ICCP classification this material is  telovitrinite but also called pseudovitrinite. The slit structures, in this case perpendicular to the long axis of the cell structure, are common in this maceral.
