Plate P14. Suberinite, fungal tissues. 1. T5819; Hole 1116D; 703.23 mbsf. Fungal resting spore (sclerotium). Occurrences of sclerotia and teleutospores are highly characteristic of Tertiary and Holocene coals and, to a lesser extent, organic-rich sediments. Although similar fungi were present at earlier times, these highly chitinized bodies were not preserved (reflected light; field width = 0.22 mm; mean vitrinite reflectance = 0.39%; sclerotinite reflectance = 1.20%). 2. T5828; Hole 1115D; 241.48 mbsf. Telovitrinite (dark gray) with abundant pale gray fungal hyphae invading the tissues. Fungal attack is common, but the hyphae do not always show optical contrast as strong as in this field (reflected light; field width = 0.22 mm; mean telovitrinite reflectance = 0.15%; fungal tissue reflectance = 0.66%). 3. T5818; Hole 1109D; 696.89 mbsf. Prominent layer of strongly fluorescing suberinite is shaly coal. The dark layers and lenses are vitrinite, and abundant resinite and liptodetrinite are also present (reflected light; field width = 0.22 mm; mean vitrinite reflectance = 0.28%). 4. T5817; Hole 1109D; 688.21 mbsf. Wood tissue showing the outer layers with suberinite present in the upper part of the field and gelified tissue in the lower part of the field (reflected light; field width = 0.22 mm; mean vitrinite reflectance = 0.40%).
