SPECIES, AUTHORITY T. ovatus (Venkatachala & Kar) Kalgutkar & Jansonius 2000
LOCATION Bore-hole No. 14, Matanamadh, Kutch, Gujarat, India.
ORIG DESCRIPTION* Perithecium dark brown, subcircular-circular, size range 60-150 µm. Central part of perithecium lighter, comprising 4-5 hexagonal cells, surrounded by a thick, at least two-layered, dark, plate-like, well-defined, rounded area consisting of square-hexagonal cells. Remaining part of perithecium one-layered and comprising square to somewhat hexagonal pseudoparenchymatous cells of unequal length and width, produced by the radiating interconnected hyphae. Outer margin slightly undulating, not thickened.
COMMENTS* Microthyriacites fimbriatus Cookson 1947a resembles Sphaerialites ovatus in the presence of thickened, dark-colored area surrounding the central part of the perithecium. The hyphae in M. fimbriatus producing pseudoparenchymatous cells also radiate from a central group of hexagonal cells; but this species can easily be differentiated by its very thick hyphae and small size of the cells in the inner as well as in the outer part of the perithecium.
