SPECIES, AUTHORITY T. echinatus (Rao & Ramanujam) Kalgutkar & Jansonius 2000
LOCATION Lignite from Warkalli, India.
ORIG DESCRIPTION* Ascomata flattened, dimidiate, rounded, margin even and firm; 90-115 µm in diameter; ostiolate, ostiole centric, 11-14 µm in diameter, elevated on a thick border of 4-5 layers of thick-walled cells, inner layer of ostiole border with 15-22 prominent spinous processes, spines 5-8 µm long, 2.0-2.5 µm broad at the base. Rest of the fruiting body with radially aligned squarish to rectangular cells, 3.0-3.5 x 2.5-4.5 µm in size, radial walls of these cells thick-walled.
COMMENTS* Fruit bodies of this type have been recovered from the Warkalli lignite. Notothyrites echinatus differs from other known species in the possession of prominent spinous processes projecting into the ostiole. Notothyrites setifer Cookson 1947a recorded from the Warkalli lignites (Ramanujam & Rao, 1973) is characterized by short denticular to conical processes.

K&J REMARKS Reddy et al. 1982 proposed the combination Trichothyrites echinatus (Cookson), but did not provide the basionym or bibliographic details, and hence did not validly publish this combination.
