Definition of telinite

i. This term was proposed by W.J. Jongmans (1935) to designate a vitrinite showing cellular structure. The Nomenclature Subcommittee of the International Committee for Coal Petrology decided in 1957 to use the term telinite only for the cell walls seen in vitrinite. Only in this manner can telinite be rightly included among the macerals. Telinite shows more or less clearly defined cell structure (wood, periderm, etc.) sometimes deformed. The cells are generally filled with collinite, but the structure is better shown when the cells are either empty or filled by material such as resinite, fine micrinite, clay minerals, etc.
