Description: Telovitrinite (pseudovitrinite) on the right and detrovitrinite on the left of frame. Note the remnant cell structure and the serrated edges along the fracture in the telovitrinite. The lower reflectance and the included macerals of liptinite (dark) and inertinite (bright) in the detrovitrinite are characteristic of this maceral.
