SPECIES, AUTHORITY T. keralensis (Rao & Ramanujam) Kalgutkar & Jansonius 2000
LOCATION Lignite from Warkalli, India.
ORIG DESCRIPTION* Ascomata rounded, dimidiate, margin even to crenate, firm, 58-85 µm in diameter. Ostiolate, ostiole centric, round, 7-9 µm in diameter, with a prominent border of 2-3 layers of thick-walled dark brown cells. Hyphopodiate free mycelial shreds near ostiole border, rest of ascomata with strictly radially arranged, squarish to rectangular 2-4 µm wide cells; outer walls of marginal cells thickened. Ascospores unknown.
COMMENTS* Fruiting bodies of this type are very common in certain samples of Warkalli lignites and show a wide range of variation in their size. One of the constant characters is the presence of hyphopodiate mycelial shreds in the vicinity of the ostiole border. No definite organic connection of these hyphal branches and the border cells of the ostiole could, however, be established. Asterothyrites sinuatus and A. delicatissimus described from Australia (Cookson, 1947a) are non-ostiolate.

K&J REMARKS This species is ostiolate and shows a definite dark, thickened (?) rim around the ostiole.
