Coal Ball an overview ScienceDirect Topics

Because coal balls are accumulations of (degrading) plant material (technically peat), they also are an excellent source of various forms of decaying organisms, including fungi. Numerous fungal remains have been found in coal balls, including hyphae, spores, and various types of reproductive structures. Initially fungi were discovered in thin sections along with the plant parts that were the
